Abstract

Abstract The paper is concerned with the application of mathematical programming techniques to a variety of structural plasticity problems. The incremental and finite elastoplastic analysis problems, as well as the plastic limit analysis problem, are formulated as a variety of linear complementarity, quadratic, linear and nonlinear programming problems. A unified computational scheme is presented, and comparisons are made between the mathematical programming techniques and the so-called “direct” methods for nonlinear finite element analysis.
