An Experimental Study of Instability Phenomena in the Initiation of Plastic Waves in Long Rods

A series of experiments are considered for stress-time histories at the impact face for wave propagation in long rods. From these data it is shown that the finite deformation mode and transition stability structure of the writer’s generalized parabolic stress-strain function is important in the problem of finite amplitude non-linear wave initiation and growth at the impact face and in the three-dimensional first diameter when considering the symmetrical free-flight impact of identical long cylindrical rods.
