Strain

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Strain, abbreviated as \(\epsilon\) (Greek symbol epsilon), also called linear strain or longitudinal strain, is the deformation, stretched or compressed, of a material compared to its original length.

Strain formula

\(\large{ \epsilon = \frac{ \Delta l }{ l }  }\)

Where:

\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain

\(\large{ l }\) = length

\(\large{ \Delta l }\) = length differential

Solve for:

\(\large{ l = \frac{ \Delta l }{ \epsilon }  }\)

\(\large{ \Delta l =  \epsilon \; l  }\)
