陶瓷挤压凹模的强度分析

Analysis on the Strength of Ceramic Extrusion Dies

编制了通用的二维有限元程序，应用此程序对承受内压力、温度应力时的陶瓷－钢挤压组合凹模进行力学分析，并在此基础上提出了设计陶瓷型模具的理论与实践的一些普遍问题。

The authors of this paper present a common two-dimensional FEM (finite element methods)program and apply the program to analyze the problem of ceramic-steel combined dies which bearing the internal pressure and thermostress, on the basis of the analysis, the authors put forward some general theoretical and practical problems in the design of ceramic dies.
