N2 - In the past, inelastic finite element structural analyses were performed largely based on the classical concept of creep and plasticity. Recently, some attempts have been made to incorporate a specific type of viscoplastic theories into finite element codes for structural analysis. In this paper, three integration schemes are implemented into a nonlinear finite element program to study their numerical efficiency pertaining to finite element analysis. Moreover, four viscoplastic models, namely, those due to Walker, Miller, Krieg-Swearingen-Rohde, and Robinson, were implemented into a finite element program for nonlinear analysis.
