ELASTO-PLASTIC STRESS ANALYSIS. A GENERALIZATION FOR VARIOUS CONSTITUTIVE RELATIONS INCLUDING STRAIN SOFTENING

SEVERAL SIMILAR PROCESSES FOR SOLVING ELASTO-PLASTIC PROBLEMS ARE DISCUSSED IN THE CONTEXT OF A GENERAL FORMULATION WHICH INCLUDES ASSOCIATED AND NON- ASSOCIATED PLASTICITY RELATIONS AND STRAIN HARDENING AS WELL AS STRAIN SOFTENING BEHAVIOR. ADVANTAGES OF THE "INITIAL STRESS" PROCESS ARE EMPHASIZED FOR A WIDE CATEGORY OF PROBLEMS; THE ISOPARAMETRIC FORMULATION IS USED THROUGHOUT. THIS PROCESS, RENAMED THE "RESIDUAL FORCE METHOD", FORMS THE BASIS OF THIS PAPER; IT IS DEMONSTRATED THAT FURTHER IMPROVEMENTS CAN BE OBTAINED BY SUITABLE MODIFICATIONS. /DOT/
