In materials science, strain rate is the change in strain (deformation) of a material with respect to time. The strain rate at some point within the material measures the rate at which the distances of adjacent parcels of the material change with time in the neighborhood of that point. It comprises both the rate at which … See more The definition of strain rate was first introduced in 1867 by American metallurgist Jade LeCocq, who defined it as "the rate at which strain occurs. It is the time rate of change of strain." In physics the strain rate is … See more Similarly, the shear strain rate is the derivative with respect to time of the shear strain. Engineering shear strain can be defined as the angular displacement created by an applied shear stress, $${\displaystyle \tau }$$.
