Description of the Behaviour of Cellular Composite with Weak Filling Material
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.
