Plasticity of Three-Dimensional Foams,macroscopic material properties (elastic constants and yield stress). In the following, a strategy to determine the influence of the hydrostatic stress on the yield behaviour is proposed and conceptionally realised by a state of plane strain and a state of uniaxial strain. In addition, alternative w

Fracture Mechanics of Cellular Solids, intension up to the brittle fracture, so they can be treated using Linear Elastic Fracture Mechanics. This chapter presents the Linear Elastic Fracture Mechanics parameters and criteria with application for foam materials. Methods for experimental determination for tear strength and fracture toughn

Finite Element Modeling of Cellular Materials,e of components made from them. Consequently, the effective behavior of cellular materials is rooted in the mechanical behavior of the struts and/or cell walls on the length scale of individual cells. These lecture notes describe methods of modeling cellular materials by the finite element method. T

Plasticity of Three-Dimensional Foams,pherical and the deviatoric part and the use of stress invariants to describe the physical content of the stress tensor. In the next part, the elastic behaviour of isotropic materials based on generalised Hooke’s law is summarised and a notation appropriate for computer implementation is introduced.
