English abstract:
Cellular materials are characterized by a low apparent density and a discrete micro-structure which is on a distinctly lower length-scale than the one 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 methods. Topics include the setup of micro-mechanical models for open and closed/cell foams as well as sintered hollow-sphere foam, the transition between the different mechanical length scales, and the optimization of the density distribution in components made from functionally graded foam.
