Abstract

The densification behavior of sintered aluminium has been investigated by performing simulation studies using DEFORM 2D software. The results have been compared with the experimental values. The deformation characteristics of the sintered preforms have been studied and the relationship between the various stresses such as true stress, true strain, hoop stress, hoop strain, hydrostatic stress, hydrostatic strain, effective stress, effective strain and relative density in both the experimental and simulations has been discussed for uniaxial, plane stress and triaxial stress state conditions. A good agreement is found between the experimental and simulation results.
