Abstract

In the paper multi-scale modeling of the foamed metal structures using numerical homogenization algorithm is prescribed. The first, numerical model of heterogeneous porous simplified structures of typical foamed metal, based on the FEM was built. Next, a micro RVE model representing elementary volume of macroscopic model was constructed. Material parameters of the considered structure were determined with use of numerical homogenization algorithm. In the work the different RVE models of structure were created and their properties were compared at different relative density, different numbers and the size and structure of the arrangement of voids.
