摘要
以碳酸钙粒子（CaCO3）填充聚苯硫醚（PPS）粒子为研究对象，用ANSYS/LS-DYNA软件对复合材料冲击过程中界面应力分布进行了有限元分析。结果表明：在粒子的赤道处，正应力、剪切应力和等效应力均为最大，朝极点方向迅速减小，在距赤道约0.5-2.0μm之间达致最低点，然后趋于平缓或略微回升，并介绍了PPS/CaCO3复合材料在冲击载荷下失效或断裂的主要机理。
Interracial stress distribution in the composite of CaCO3 particle filled PPS under impact loads is analyzed with finite element model by the aid of ANSYSfLS-DYNA software, The results show that at the equator, the normal stress, shear stress and equivalent stress reach the maximum, and then decrease sharply along interface towards the polar point, they reach to the minimum at the range of 0.5 - 2.0 μm from the equator, and then it tends to stability or a little up. The fracture and its mechanism or causing of PPSICaCO3 composite under impact loads are discussed.
