摘要

分析了JH2强度模型的局限性;使用Autodyn程序,采用SPH算法,基于JH2模型和Rankine模型的复合强度模型,对陶瓷靶的冲击破坏进行了数值模拟。结果表明,复合强度模型较全面地描述了陶瓷材料在冲击荷载作用下的破坏机制,采用复合强度模型可很好的模拟陶瓷靶的冲击破坏形态。

Abstract

The limitation of JH2 strength model was analyzed. With Autodyn code and SPH algorithm, based on the combined strength model of JH2 model and Rankine model, the damage of the ceramic target under impact was numerically simulated. The results show that the combined strength model fully describes the failure mechanism of ceramic material, and also the ceramic target's damage profile is well simulated with the combined strength model.

Key words： combined strength model; ceramic; impact; damage
