Change Length due to Strain

The Change in Length due to Strain calculator computes the change in length based on an original length and a strain factor.

INSTRUCTIONS: Choose units and enter the following:

• (ε) Strain
• (L₀) Initial Length

Change in Length from Strain (ΔL): The calculator returns the change in length in millimeters. However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Strain is the deformation of a solid due to stress.  Engineering stress 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`).

The formula for the deformation in change of length caused by strain:

     ΔL =  L • ε

where:

• ΔL is the change in elongation from strain.
• ε is strain
• L is the initial length
