Abstract

This paper deals with modelling and simulation of plastic ductile damage evolution in thin-walled structures and its effect on the load-carrying behaviour in the geometrically and physically non-linear range of deformation. In this context, gradual stiffness degradation, damage evolution, local failure initiation, and final collapse of the structure are problems of primary interest. The approach adopted accounts for elastic-plastic material behaviour, isotropic as well as kinematic hardening, material damage, finite displacements and finite rotations. Finite element simulations illustrate the effect of material damage on the load carrying behaviour of thin-walled structures. 1 Introduction The accurate determination of the ultimate load carrying capacity of thin-walled structures in the geometrically and physicall
