Experimentally, it has been observed for single crystals of a number of metals that the critical resolved shear stress Tess is a function of the dislocation density po as Terss = to +AVPD where To and A are constants. For copper, the critical resolved shear stress is 2,10 MPa (305 psi) at a dislocation density of 10 mm? If it is known that the value of A for copper is 6.35 x 10-3 MPa-mm (0.92 psi-mm), compute the Tess at a dislocation density of 10' mm? 1 of 5 TI Dashboard SEE Calendar TO DO Notifications Inbox
