Regularization and perturbation technique to solve plasticity problems
Source abstract
Abstract
This paper investigates new procedures to solve plasticity problems by using the asymptotic numerical method (ANM). As the elastic-plastic behavior involves two unilateral conditions, we replace these two conditions by regular functions depending upon the stress field and its time derivative which permits one to take into account elastic-plastic transition and elastic unloading. Several applications in structural plasticity problems are presented to assess the ability of the proposed algorithm.
