| 摘 要： | 分析了粉末体屈服准则建立的出发点和假设条件,认为泊松比与相对密度的关系、粉末体屈服准则的实验验证及相对密度与屈服应力的关系是粉末体屈服准则的主要研究内容。并由此进行了理论分析和实验研究。

| 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. |
