Numerical analysis of uncertainties in the effective material behaviour of disordered structural foams

Abstract
The present contribution is concerned with a numerical analysis of the uncertainties in the structural response of three-dimensional structural foams with partially open cells. The effective thermo mechanical material response is determined by means of an energy based homogenization procedure. Stochastic effects in the geometry and topology of the microstructure are treated by means of a repeated analysis of small-scale representative volume elements with prescribed relative density and prescribed cell size distribution. The results are evaluated by stochastic methods.
