	A numerical\&nbsp;homogenization\&nbsp;technique and morphological analysis based on the finite element method are used to compute mechanical properties of porous materials. This is achieved by considering two{\textendash}dimensional matrix containing random distribution of identical non{\textendash}overlapping circular or elliptical voids. Several microstructure configurations are obtained by varying the voids morphology and the porosity of the matrix. The notion of the\&nbsp;representative volume element\&nbsp;is used for numerical simulations in order to estimate the morphology effects of the voids on the effective ultimate tensile strength of the called\&nbsp;Lotus{\textendash}Type Porous Metals. A confrontation of the obtained numerical results of the representative microstructures for different morphologies of voids and different porosities to an analytical model and experimental data is performed. Finally, a formula improving the Boccaccini model is proposed to estimate effective tensile strength of porous metals taking into account the voids morphology.
