The Strain calculator computes the ratio of change in length to original length.
INSTRUCTIONS: Choose units and enter the following:
Strain (S): The calculator return the ratio of strain as a real number. However, this can be automatically converted to percentage via the pull-down menu.
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.
ε = ΔL / L
Engineering strain is defined in terms of the change in length of a physical element (`Delta L`)divided by the original length of the physical element (`L_0`).
