Abstract:

Identifer Dislocations. Conditions for determining the motion of dislocation arrays from plasticity solutions were established. The predicted mode of deform tion was observed in Al and in AgCl specimens under torsion. Observations of AgCl under plastic reversed stress showed the slip usually did not reverse on a given plane, that further forward slip could occur on one pla e, that co sid r ble disorganization of the crystal developed before fracture, th t cracking can occur on planes of high shear stress without appreciable motion normal to the surface, and that structural inhomogeneities reached a scale of the order of 0.1 mm. Crack initiation and propagation rates were reasonably well correlated with a crack growth theory based on continuum plasticity. Author
