分析了金属粉末模压下的致密化过程。将岩石力学中的ＣａｍＣｌａｙ 模型用于该过程的分析，并与常用的Ｆｅｌｃｋ 和Ｓｈｉｍａ 模型进行比较。经实验验证得知： ＣａｍＣｌａｙ 模型能够较精确地分析金属粉末的模压致密化过程， 而Ｆｅｌｃｋ 和Ｓｈｉｍａ 模型的分析误差较大 The densification process under metal powder molding was analyzed. The CamClay model in rock mechanics was used for the analysis of this process and compared with the commonly used Felck and Shima models. The experimental verification shows that: Cam-Clay model can more accurately analyze the metal powder compacting densification process, and Felck and Shima model analysis error larger
