Elastoplastic Finite Element Analysis for Porous Metals

Abstract

The elastoplastic finite element method for the deformation of porous metals has been newly formulated using the yield condition advanced by Lee and Kim. Changes in geometries and densities of porous metals, and upsetting loads with upsetting strain have been calculated. The Brinell hardnesses of porous metals with various densities dependent on indenting geometries have been analysed. The calculated results were in very good agreement with the measured data. PM/0632
