This paper presents the results of finite element simulations of isostatic pressing process using material parameters of a uniaxial compaction in order to fit the material model. This has been done through the use of a Drucker-Prager/cap model within the commercial finite element code ABAQUS(R). For this study, it is simulated the isostatic pressing of ceramic spheres for hip implant stem. The simulations yield to a good agreement with measured manufactured components.
