Abstract

A considerable progress in theoretical framework of ElasticVisco-Plastic model (EVP) has been achieved in the last decades. In order to extend these models into application, appropriate numerical algorithms for the nonlinear constitutive equations of an EVP are investigated in this study. The EVP model is incorporated into the Plaxis software. The performances of the implicit time-stepping algorithm and explicit time-stepping algorithm are examined in details. In addition, the stability and accuracy of the EVP model are studied with different algorithms are evaluated and the validation of the EVP model is examined by comparing the simulation results with previous experimental results, demonstrating a considerable agreement.
