Supposing there is no interaction between solute atoms, the feature ofdislocation motion and the distribution of solutes are obtained at different external stresses in the dynamic simulation.
动态模拟中假设溶质原子之间没有相互作用，得到在不同的外加应力下位错的运动特征和溶质原子的分布状态。

The numerical examples are provided to show the influences of the material properties, the wedge Angle, dislocation position and the crack length on the interaction.
最后通过数值算例，针对不同问题讨论了材料常数、楔口角度、裂纹长度对相互作用的影响。

In the second chapter, the interaction among a screw dislocation, circular interfacial crack and inclusion is solved based on the electromechanical coupling relation of piezoelectric material.
