摘 要: 分析了金屬粉末模壓下的致密化過程。將巖石力學(xué)中的Cam-Clay模型用于該過程的分析，并與常用的Fleck和Shima模型進行比較。經(jīng)實驗驗證得知：Cam-Clay模型能夠較精確地分析金屬粉末的模壓致密化過程，而Felck和Shima模型的分析誤差較大。

Abstract:Die compaction densification behavior of metal powders was analyzed. Cam-Clay model in rock mechanics was introduced, and compared with often-used Shima model and Fleck model. From experimental comparison, it revealed that Cam-Clay model can simulate well die compaction densification behavior of metal powders, while Shima model and Fleck model can't.
Key words: metal powder; die compaction; densification behavior; Cam-Clay model
