Recently, the demand to analyse the performance of metal foams is increased due to the increase in use of them in different engineering applications. In this study, two types of porous metals were finite element (FE) modelled in terms of pore size and distribution (uniform and random) with three pores’ volume fractions (15, 40, and 65%). Uniformly distributed pores were analysed based on a tetrahedron cell. Conversely, the data of the size and location of each pore in the random porous metal were generated using Microsoft excel software. Two types of test samples were modelled, compressive and bending. The results showed that the location of the maximum Von-Mises stress for uniformly pores metal in the compression test was located in the vertical walls between pores. Whereas it located in the upper or the lower surface at the centre of the bending sample. The samples with random distribution pores show more complex behaviour due to the non-uniform thickness of walls between the pores. However, the maximum stress found to be located at the thinner vertical walls between the pores for the compression sample. Nevertheless, the maximum stress was located at the thinnest horizontal walls, near the location of the maximum bending moment.
