Experimentally, it has been observed for single crystals of a

Experimentally, it has been observed for single crystals of a Experimentally, it has been observed for single crystals of a number of metals that the critical resolved shear stress tcrss is a function of the dislocation density ?D as where t0 and A are constants. For copper, the critical resolved shear stress is 2.10MPa (305psi) […]
