We use complex variable methods to derive analytic solutions to the problem associated with the interaction between a screw dislocation and a completely coated semi‐infinite anticrack. The two sides of the anticrack or rigid line inclusion are perfectly bonded to the surrounding coating, which is also perfectly bonded to its neighboring matrix. The screw dislocation can be located anywhere in the composite structure. We obtain explicit expressions for the resultant stress intensity factor characterizing the square root singularity in the stress distribution at the anticrack tip, the resultant anticrack contraction force, which is always negative, and the image force acting on the screw dislocation.

螺钉脱位与完全涂覆的半无限抗裂之间的相互作用

我们使用复杂的变量方法来得出与螺钉脱位和完全涂覆的半无限抗裂纹之间的相互作用相关的问题的解析解。防裂或刚性线夹杂物的两侧都与周围的涂层完美粘合，而周围的涂层也与周围的涂层完美粘合。螺钉错位可以位于复合结构的任何位置。我们获得了表示抗裂尖端应力分布的平方根奇异性的合成应力强度因子，合成抗裂收缩力（始终为负）以及作用在螺钉位错上的像力的显式表达式。
