MathLiveLinear strain
Linear strain gives the relative change in length of a material, found by dividing the change in length by the original length. It is used in solid mechanics and materials science to describe stretching or compression, whether caused by applied loads, thermal expansion, or other effects.
\varepsilon = \frac{\Delta l}{l}What the symbols mean
| linear strain (dimensionless) | |
| change in length (m) | |
| original length (m) |
