Abstract

The structural dynamic models for finite deformation hypoelasticity/hypoelasto-plasticity problems were discussed. A nonlinearly explicit second-order accurate L-stable methodology and implementation procedures for total/updated Lagrangian formulations to analyze the models were presented. An explicit exact integration procedure for a particular rate form constitutive equation for the problems was provided. Results of a numerical example showed the robustness of the developments for nonlinear dynamic applications.
