What Does CRSS Stand For?

CRSS stands for Critical Resolved Shear Stress

CRSS, or Critical Resolved Shear Stress, is a material property representing the minimum shear stress required to initiate slip in a crystalline material under applied loading conditions. It is a crucial parameter in understanding plastic deformation, particularly in metals, as it influences yield strength and flow behavior. The CRSS is determined by the material's microstructure, temperature, and strain rate, and plays a key role in predicting the onset of plasticity and the overall mechanical performance of materials.
