Time-independent plastic flow in both single crystals and polycrystals is defined by a critical/maximum resolved shear stress (τCRSS), initiating dislocation migration along parallel slip planes of a single slip system, thereby defining the transition from elastic to plastic deformation behavior in crystalline materials. The critical resolved shear stress for single crystals is defined by Schmid’s la… WebFeb 17, 2024 · Crystal Plasticity Basics Part 1 Not Real Engineering 11.3K subscribers Subscribe 11K views 2 years ago Crystal Plasticity This video talks about the basic concepts of …
