| Abstract: | Based on the research of mechanical model of ZrO_2 powder compressing process, with finite element software MSC.Marc, analysis of flow behaviors, rules as well as density of an axisymmetric block of ZrO_2 powder in a process of compression are made. The geometric shape, stress and strain field together with density distribution are got in the process of prototyping, causes of quality deficiency are identified with these results, and an ideal shape of die is confirmed rapidly and effectively. |
