Some Recently Developed Aspects of Plastic Wave Analysis.
Abstract
The analysis of the propagation of plastic waves for one-dimensional stress and one-dimensional strain are compared and contrasted. The former pertains to waves along a thin rod or wire, the latter to waves through a slab. The influence of finite strain is studied in some detail. The theory of the propagation of plastic waves of combined stresses is reviewed with particular emphasis on the waves propagated in one space dimension due to the application of perpendicular, independent, uniform shear tractions on the surface of a half-space. Solutions obtained numerically from characteristic theory are discussed, and some unexpected features of the coupling between stress components are remarked upon. Simple wave solutions are also reviewed, and aspects pertinent to tests for dynamic plastic material characteristics are mentioned. Some recent work clarifying aspects of the determination of elastic-plastic boundaries is also described. (Author)
