Abstract
Various methods of analysis, based on different assumptions and degrees of approximation, have been developed for the solution of plastic deformation problems. The choice of a specific method depends upon the information sought. In this paper, the problems of friction, deformation characteristics, and fracturing involved in plastic deformation processes are discussed, using three different methods of analysis: the upper-bound, the slip-line, and the finite element methods.
