WebJun 24, 2024 · Strain-rate sensitivity (SRS) of flow stress is an important parameter for deformation mechanism of materials. Definition of SRS is based on incremental changes in strain rate during tests performed at a fixed temperature and fixed microstructure, to determine corresponding changes in flow stress. WebAs the name implies, shear stress refers to the action of a force applied to a material, as indicated by equation 1. 𝞽 = F/A (1) where 𝞽 is the shear stress, F is the applied force, and A is the cross-sectional area parallel to the direction of the applied force. The above equation gives the average shear stress per unit area.

"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.
