RATE EFFECTS ON RESIDUAL STRENGTH OF FLAWED STRUCTURES AND MATERIALS

The literature is reviewed with respect to tests conducted to investigate crack re-initiation under dynamic loads and arrest of a running crack; metallurgical sources of rate effects; available data for aerospace engineering materials; and mechanical sources of rate effects, dynamic crack tip stresses and kinetic energy effects. Conclusions are drawn and recommendations made.
