COMPUTER SOLUTION OF PLASTICITY PROBLEMS

In recent years, finite-element methods have proved to be a very useful tool in obtaining solutions to problems of practical importance for both elastic and inelastic structures. Because the need for solutions is so great, and because the results predicted by finite-element solutions are reasonable, primary interest has been in the establishment of efficient computer programs for the solution of large scale problems. As a result, some theoretical considerations which may be important in extended applications of the methods have tended to be overlooked. The present paper reviews the current state of the art, focuses on some of these questions and recent work that has been done towards obtaining answers, and suggests some desirable directions for future research.
