Progressive Fragment Modeling of the Failure Wave in Ceramics Under Planar Impact Loading

  • 摘要: 从多晶陶瓷材料细观结构非均匀性及其导致的应力奇异性分析出发,建立了陶瓷材料在冲击压缩下的本构关系,以及以表征材料损伤和破坏的非弹性体积应变为传播特征的破坏波控制方程,破坏层的非弹性体积应变包括由微裂纹成核、扩展引起的膨胀体积应变和由气孔塌陷引起的压缩体积应变两部分.结合92.93%氧化铝陶瓷板碰撞试验,数值模拟了冲击压缩下陶瓷材料中破坏波的传播过程,并对跨越破坏波阵面应力历程和剪切强度的变化规律进行了分析.
