Abstract
Up to now, some explicit approximate integration schemes based on exponential maps, for non-hardening material obeying DruckerePrager’s criterion, have been presented. Two new exponential-based approximate formulations, for associative DruckerePrager plasticity are developed in this article. Both are consistent and explicit algorithms. The linear isotropic and Prager’s kinematic hardening behavior are assumed. Furthermore, an accurate solution for the constitutive equations is derived. The accuracies of the suggested approximate algorithms are assessed by creating related iso-error maps. In addition, by using piecewise strain load histories, and calculating computation times, the robustness and efficiency of the formulations are demonstrated.
