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 pore...

Even though (WAAM) has demonstrated its ability to meet the demands of manufacture components on medium-to-large size made of (Al) for the automotive and other related industries, WAAM cannot currently use as a complete production procedure due to practical issues such as mechanical properties that aren’t matched and the presence of significant residual stresses. the AM technologies offer promising new benefits with the MMCs as a solution for some challenges. This article reviews the MMCs Mixing technique and their critical issues, AM classification, WAAM process with advantages and challenges. also reviews WAAM of some AMCs with different reinforcements and power sources. The results of the study of the influence of reinforcement particles on the structure showed that they were changed grains...
