What is Strain Rate Calculator?
What
Strain rate shows how fast a material changes shape. It measures the speed of deformation over time.
Why
Engineers use strain rate to test materials, design safe structures, and understand how things break or bend.
Applications
Used in material testing, earthquake studies, manufacturing, polymer processing, and metal forming.
Simple Explanation: Think of pulling a rubber band. If you pull it slowly, that is a low strain rate. If you pull it very fast, that is a high strain rate. The strain rate measures this speed of stretching or squeezing.
Strain rate is a very important idea in engineering and science. When you stretch, squeeze, or bend something, the speed matters a lot. This speed is called the strain rate.
For example, a metal bar might bend easily when you push it slowly. But if you hit it fast, it might break instead. This happens because the strain rate is different. Engineers need to know this to make safe products.
Our strain rate converter helps you change between different units. You can convert from per second to per minute. You can also convert to per hour or other units. This makes your work easier and faster.
The strain rate calculator is free to use. You do not need to sign up. Just enter your value and select the units. The answer appears right away. This tool saves you time and helps avoid mistakes.
Understanding Strain Rate Units
Learn about different strain rate units. Each unit has a specific use in engineering and science.
Per Second (s⁻¹)
This is the most common unit for strain rate. It means how much the material changes in one second. If the strain rate is 0.01 s⁻¹, the material deforms by 1% every second.
Per Minute (min⁻¹)
This unit shows deformation per minute. It is useful for slower tests. To convert from per second to per minute, multiply by 60. For example, 1 s⁻¹ equals 60 min⁻¹.
Per Hour (hr⁻¹)
This unit is for very slow processes. Some materials take hours to deform. To convert from per second to per hour, multiply by 3600. For example, 1 s⁻¹ equals 3600 hr⁻¹.
Percent per Second (%/s)
This unit is easy to understand. It shows the percentage change per second. If a material has 2%/s strain rate, it grows or shrinks by 2% each second.
Microstrain per Second (με/s)
This unit is for very small changes. One microstrain is 0.000001 strain. This is useful when measuring tiny deformations in sensitive materials or structures.

How Materials Behave at Different Strain Rates
Materials act differently when you change the strain rate. Understanding this helps you choose the right material for your project.
Different materials act differently when you change the strain rate. This is very important to know. Let me explain with simple examples.
Low Strain Rate (Slow Deformation)
When you apply force slowly, materials have time to adjust. They can stretch more before breaking. This is like slowly pulling taffy candy. It stretches a lot without breaking.
Typical Range: 0.00001 to 0.001 s⁻¹
Example: Creep tests use strain rates around 0.0001 s⁻¹. This is very slow. It helps us understand how materials behave over long periods like years.
Medium Strain Rate (Normal Testing)
Most material tests use medium strain rates. This gives us standard results. We can compare different materials fairly. The typical range is 0.001 to 0.1 s⁻¹.
Typical Range: 0.001 to 0.1 s⁻¹
Example: Tensile testing in labs usually uses 0.001 s⁻¹. This is the standard speed for testing metal strength. Most engineering data comes from this strain rate.
High Strain Rate (Fast Impact)
When force is applied very fast, materials behave differently. They often become stronger but more brittle. They can break suddenly without much warning.
Typical Range: 100 to 10,000 s⁻¹
Example: Car crash tests use strain rates of 1000 s⁻¹ or higher. This shows how car parts behave in real accidents. Safety designs depend on this data.
Strain Rate Conversion Formulas
Per Second to Per Minute
min⁻¹ = s⁻¹ × 60
Example: 0.01 s⁻¹ = 0.01 × 60 = 0.6 min⁻¹
Per Minute to Per Hour
hr⁻¹ = min⁻¹ × 60
Example: 5 min⁻¹ = 5 × 60 = 300 hr⁻¹
Strain Rate Definition
ε̇ = dε/dt
Rate of change of strain with time
Engineering Strain Rate
ε̇ₑ = (1/L₀) × (dL/dt)
L₀ = original length, dL/dt = length change rate

Sports Equipment
Tennis rackets, golf clubs, and helmets all experience impacts. These impacts have high strain rates. Manufacturers test materials to make sure they perform well. A good helmet must absorb shock at high strain rates to protect your head.
Frequently Asked Questions About Strain Rate
Get answers to common questions about strain rate. These simple explanations help you understand strain rate better.
What is strain rate?
Strain rate is how fast a material changes shape. It measures the speed of deformation. For example, if you stretch a rubber band quickly, that's a high strain rate.
How do you calculate strain rate?
Strain rate = change in strain / change in time. The formula is ε̇ = dε/dt. It tells you how much the material deforms per second.
What is the unit of strain rate?
The most common unit is per second (s⁻¹). Other units include per minute (min⁻¹), per hour (hr⁻¹), percent per second (%/s), and microstrain per second (με/s).
Why is strain rate important?
Materials behave differently at different strain rates. A material might be strong when pulled slowly but break easily when pulled fast. Engineers need to know this for safe designs.
What is a typical strain rate for material testing?
Standard tensile tests use 0.001 to 0.01 s⁻¹. Creep tests use very slow rates like 0.0001 s⁻¹. Impact tests use very fast rates like 1000 s⁻¹ or higher.
How do I convert s⁻¹ to min⁻¹?
Multiply the value in s⁻¹ by 60. For example, 0.01 s⁻¹ = 0.01 × 60 = 0.6 min⁻¹. This is because there are 60 seconds in one minute.
What is the difference between strain and strain rate?
Strain is how much a material has deformed (like 5% longer). Strain rate is how fast it deforms (like 0.01 per second). Strain is a measure, strain rate is a speed.
Can strain rate be negative?
Yes, a negative strain rate means the material is getting shorter or compressing instead of stretching. The sign shows the direction of deformation.

Tips for Accurate Strain Rate Measurements
Getting accurate strain rate data is important. Follow these tips to ensure your measurements are correct and reliable.
✓ Use the Right Equipment
Make sure your testing machine is calibrated. Old or broken equipment gives wrong results. Check your tools before each test. This ensures accurate strain rate measurements.
✓ Control Temperature
Temperature affects how materials behave. Hot materials deform differently than cold ones. Keep the temperature steady during your test. Record the temperature with your strain rate data.
✓ Prepare Samples Properly
Cut samples to the right size and shape. Rough edges or cracks can affect results. Clean the sample surface. Good preparation leads to reliable strain rate data.
✓ Record Everything
Write down all test conditions. Note the strain rate, temperature, humidity, and sample details. Good records help you understand your results later. They also help others repeat your work.
Strain Rate in Different Materials
Different materials respond to strain rate in unique ways. Understanding these differences helps you choose the right material for your needs.
Metals and Alloys
Metals like steel and aluminum are sensitive to strain rate. At low strain rates, they deform smoothly. At high strain rates, they become stronger but more brittle. This is called strain rate hardening.
Common Uses: Car bodies, airplane parts, building frames, and bridges all use metals tested at different strain rates.
Polymers and Plastics
Plastics are very sensitive to strain rate. They can be soft and flexible at low strain rates. But at high strain rates, they can become hard and crack easily. Temperature also plays a big role.
Common Uses: Plastic bottles, phone cases, car dashboards, and packaging materials are all designed with strain rate in mind.
Concrete and Ceramics
Concrete and ceramics are brittle materials. They break easily under tension. Strain rate affects how they crack. Fast loading can make them stronger than slow loading.
Common Uses: Buildings, roads, dams, and tiles all use concrete or ceramics. Engineers test these at different strain rates for safety.
Composites
Composite materials combine different materials. Carbon fiber and fiberglass are examples. Their behavior at different strain rates depends on the materials used and how they are combined.
Common Uses: Sports equipment, aircraft parts, wind turbine blades, and racing cars use composites tested at various strain rates.
Biological Materials
Bones, muscles, and tissues also have strain rate properties. Bones can handle slow loads well but may break under sudden impacts. This is why falls are dangerous.
Common Uses: Medical implants, prosthetics, and safety equipment are designed considering biological strain rate responses.
Industries Using Strain Rate Calculations
Many industries rely on strain rate data. Here is how different sectors use strain rate in their work.

Beginner's Guide to Strain Rate
New to strain rate? This simple guide explains everything you need to know. No technical background needed.
What Does Strain Rate Mean?
Strain rate is just a fancy way to say how fast something changes shape. Think about it like this:
- When you pull a rubber band slowly, it has a low strain rate
- When you pull it quickly, it has a high strain rate
- The strain rate tells us the speed of this pulling or pushing
Why Should I Care About Strain Rate?
Strain rate matters because materials act differently at different speeds:
- Silly putty stretches when pulled slowly but breaks when pulled fast
- Glass can bend a tiny bit when pressed slowly but shatters when hit fast
- Metal can be shaped easily at the right speed
- Knowing the strain rate helps us predict how things will break or bend
How Do I Read Strain Rate Numbers?
Strain rate numbers tell you how many times per second something changes:
- 0.001 s⁻¹ means it changes 0.001 times per second (very slow)
- 1 s⁻¹ means it changes once per second (medium speed)
- 1000 s⁻¹ means it changes 1000 times per second (very fast)
- Bigger numbers mean faster changes
When Do People Use Strain Rate?
Many people use strain rate in their daily work:
- Engineers test how strong materials are
- Factory workers control how fast machines shape products
- Scientists study earthquakes and how ground moves
- Car companies test safety in crashes
- Builders check if structures are safe
Simple Examples from Daily Life
Here are everyday examples that show strain rate in action. These examples help you understand the concept better.
🍬 Pulling Taffy Candy
When you pull taffy candy slowly, it stretches nicely. This is a low strain rate. If you pull it fast, it might break. This is a high strain rate.
Low strain rate = smooth stretching
🥤 Squeezing a Plastic Bottle
When you squeeze a water bottle slowly, it bends smoothly. When you squeeze it fast, it might crack. The speed of squeezing is the strain rate.
Fast squeeze = high strain rate
🎈 Blowing Up a Balloon
When you blow air into a balloon slowly, it expands evenly. If you blow too fast, it might pop. The speed of expansion is related to strain rate.
Slow inflation = safe expansion
🚗 Car Crash vs Parking
When you park slowly, the car bumper bends gently. In a fast crash, the same bumper crumples quickly. The crash has a much higher strain rate.
Crash = very high strain rate
🍞 Kneading Dough
When you knead bread dough slowly, it stays smooth. If you work it too fast, it might tear. Bakers control the strain rate to make perfect bread.
Gentle kneading = low strain rate
📎 Bending a Paper Clip
Bend a paper clip slowly and it bends smoothly. Bend it back and forth quickly and it breaks. The speed of bending is the strain rate.
Quick bending = material fatigue
Understanding the Numbers
Strain rate numbers can look confusing. This section makes them easy to understand.
Very Slow Strain Rates (0.00001 to 0.001 s⁻¹)
These are super slow changes. You cannot see them happening with your eyes.
Real Examples:
- A building settling into the ground over years
- A bridge sagging very slowly over time
- Plastic parts aging and changing shape
- Creep in metal pipes carrying hot fluids
Slow Strain Rates (0.001 to 0.1 s⁻¹)
These are slow but you can see the change if you watch carefully.
Real Examples:
- Testing metal strength in a lab
- Pulling a rope slowly until it breaks
- Pressing clay to shape it
- Standard material testing in factories
Medium Strain Rates (0.1 to 10 s⁻¹)
These happen at normal speeds. You can easily see the change.
Real Examples:
- Stamping metal sheets in a factory
- Molding plastic products
- Bending metal pipes
- Shaping aluminum parts
Fast Strain Rates (10 to 1000 s⁻¹)
These happen very quickly. The change is almost instant.
Real Examples:
- Hammering a nail into wood
- Dropping your phone on the floor
- A car hitting a speed bump fast
- Forging hot metal with a hammer
Very Fast Strain Rates (1000+ s⁻¹)
These are extremely fast. They happen in a blink of an eye.
Real Examples:
- Car crashes and collisions
- Explosions and blasts
- Bullets hitting armor
- High-speed manufacturing processes
Common Questions People Ask
Here are simple answers to questions people often ask about strain rate.
Is strain rate the same as speed?
Not exactly. Speed tells you how fast something moves from one place to another. Strain rate tells you how fast something changes shape. A car can have high speed but low strain rate if it is not deforming.
Do all materials care about strain rate?
Yes, but some care more than others. Plastics and rubber are very sensitive to strain rate. Metals also change behavior at different strain rates. Even concrete acts differently when loaded fast versus slow.
Can I measure strain rate at home?
It is hard to measure exact numbers at home. You need special equipment. But you can see the effects. Try pulling a rubber band slowly then quickly. You will feel the difference in how it resists.
Why do engineers test at different strain rates?
Because real life has different speeds. A bridge experiences slow loads from traffic. But it might face fast loads from earthquakes. Engineers test both to make sure the bridge is safe in all situations.
What happens if I use the wrong strain rate in a test?
You get wrong results. If you test too slow, the material might seem weaker than it really is. If you test too fast, it might seem stronger. Using the right strain rate gives you accurate data.
