Abstract—A technique is proposed to estimate the force of deformation of parts made of bronze-based powders under uniaxial compression conditions. The force is determined by a finite element method using the QForm and Abaqus/Standard programs. The results are compared with experimental results and the relative density of the new material is determined. The time to failure of the material with and without stress concentrators is estimated using the stress intensity range and the Gurson plasticity model.
