Elastic-plastic Analysis of Thin Plates with a Central Hole by the Finite Element Method

Abstract

High performance of personal computers enables to conduct complicated numerical simulations in a short time. The finite element method is one of the most effective tools especially for the numerical analysis of the elastic-plastic problem. Whereas, the photoelastic coating method is the experimental way to study the elastic-plastic behaviors of metals. In this study, authors investigate the elastic-plastic simulation of cross-shaped specimens with a central hole using the finite element software LUSAS. The results are compared with the experimental ones in the cases of the perforated plates subjected to uni-axial tension.
