The Strain calculator computes the ratio of change in length to original length.
INSTRUCTIONS: Choose units and enter the following:
- (L) This is the initial length.
- (ΔL) This is the change in length.
Strain (S): The calculator return the strain as a real number. However, this can be automatically converted to percentage via the pull-down menu.
The Math / Science
This Strain equation computes engineering strain from the simplest definition, where Strain is simply a ration of the change in length to the original length. The formula for strain is:
ε = ΔL / L
where:
- ε is strain
- ΔL is the change in elongation.
- L is the original length
Related Calculators
Engineering strain is defined in terms of the change in length of a physical element (ΔL) divided by the original length of the physical element (L).1
