Web2 Feb 2024 · Strain is the amount of deformation (either stretch or compression) caused by the stress divided by the initial length of the metal as shown in the equation ε = dl / l 0. If there is an increase in the length of a piece of metal due to stress, it is referred to as tensile strain. If there's a reduction in length, it's called compressive strain.
