Based on geometrical data of porous components obtained by computer tomography, a micromechanical unit cell model is proposed to predict the influence of porosity on mechanical properties of high performance cast alloys. Simulations of uniaxial loaded periodic unit cells are compared to experimental data of tensile tests on porous materials. In this way a relationship between some significant geometrical data of the pores and the macroscopic material parameters is obtained. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
