- Abstract
In the last 10-15 years a number of very powerful methods for general convex programming have been developed. Commonly labeled interior-point (IP) methods, these algorithms make it possible to solve a wide variety of practical, large-scale problems with moderate computational effort. One such class of problems is classical small-displacement, rate-independent elastoplasticity. In this paper we investigate the prospects of applying the IP methodology to this class of problems. In addition to applying standard IP otimizers, we also develop a slightly modified IP method which in term of generality, efficiency, and robustness appears to be fully competitive with conventional methods.
