Abstract
This paper describes some theoretical and practical aspects in formulating of basic equations of compressible metal-plasticity mainly in view of sintered materials. The yield condition for anisotropic and isotropic material behaviour is discussed, and a modified isotropic yield condition which is in good agreement for stress states with high triaxiality is introduced. Using the associated flow rule and the modified yield condition the constitutive law and evolutional equations are derived. The FEM implementation based on a weak formulation in a MIMD multiprocessing system is mentioned. Finally some numerical results of the deformation of a sintered component are presented.
