Abstract

A new compaction criterion and constitutive equations are proposed for the ceramic granule compact. Compressible behaviour and dilatancy phenomena of the ceramic granule compact can be expressed by these basic equations. Experimental methods are also proposed to determine the material constants necessary for the above-mentioned equations. Based on these equations, a numerical simulation system is developed to estimate the mechanical behaviour of a ceramic granule compact in cold isostatic pressing.

陶瓷颗粒压块在冷等静压中的力学行为
提出了一种新的陶瓷颗粒压实判据和本构方程。陶瓷颗粒致密体的可压缩特性和膨胀现象可以用这些基本方程来表示。本文还提出了确定上述方程所需材料常数的实验方法。在此基础上,建立了陶瓷颗粒压块冷等静压力学性能的数值模拟系统。
