- 論文の詳細を見る
The finite element method for plastic deformation of porous metals has been developed for the analysis of forming of sintered metal; based on the plasticity equations for porous metals and the upper bound theorem, a velocity field which minimizes the power is obtained. The stress components are calculated by the use of the incremental strain theory. Upsetting of cylindrical billets with smooth or rough tools and indentation of a flat punch into a cylindrical billet in a die are treated. The calculated load and the distributions of density and stress components show good agreements with experimental results.
