| 摘 要： | 对刚性柱面和SIC陶瓷材料平面产生滑动接触进行了有限元数值分析,以有限元软件ABAQUS作为分析平台,以扩展有限元方法(XFEM)和最大主应力判定准则对整个滑动接触过程中裂纹扩展的行为进行了模拟,得出了裂纹尖端单元的最大主应力及裂纹扩展路径和裂纹张开角,为生产实际过程中的无损探伤提供理论的测量视角。

| Abstract: | Analyse of cyclinder and SIC ceramic material at sliding contact with finite element analysis platform as ABAQUS software, it used Ex- tended Finite Element Method（XFEM） and maximum principal stress to simulate crack propagation action for the whole silding contact. It ob- tained the maximum principal stress and crack propagation path and crack growth angle direction, which provided measuring angle for practical production process＇ s nondestructive test. |
