Abstract

In this paper, a corotational Lagrangian finite element method is presented to analyze the geometric and material nonlinearity problems using degenerated shell and SOLID ELEMENTs. The formulation is based on the updated - Lagrangian conjugate stress and strain tensors with the linear and nonlinear terms to eliminate the approximation of the Cauchy stress in the finite element formulation. Linear work hardening and Prandtle-Reuss flow rule along with 1`von-Mises yield criterion is used to model material nonlinearity. To investigate the accuracy and computational efficiency of the formulation, some examples in elastic and ELASTIC-PLASTIC regime is presented. Also, the results obtained from this method are compared with those available using other corotaional finite element formulations.
