Abstract

At first, starting Point and hypothesis used to establish yielb criterion of powder compact have been analysed. Author think correlation between poisson ratio and relative density and experimental testment of the yield criterion of powder compact and relationship between yield stress and relative density are principal points to studying yield criterion of powder compact.Therefore, a series of theoretical analyses and experimental investigations for the yield criterion of powder compact have been carried out in this paper.
