Description of the Behaviour of Cellular Composite with Weak Filling Material

Part of the IUTAM Bookseries book series (IUTAMBOOK, volume 12)

Abstract

The aim of this presentation is to show the behaviour of a cellular composite material. The material is two-phase consisting of metallic, relatively rigid interfaces and weak filling material. Such type of a generic composite is used as core filler between external layers of sandwich composite material applied in aerospace engineering. We investigate the limit load of a sample varying the initial void ratio in the filling. We are using the Tvergaard-Gurson in order to describe porosity existence in the material and elasto-plastic models with the assumption of presence of the finite deformations. The geometrical model is three-dimensional.
