| 摘 要： | 运用复变函数方法研究了压电磁材料中圆柱形刚性夹杂附近运动螺型位错所激发的力场和电磁场。求得了位移、应力、应变、电场、电位移以及磁感和磁场的显式表达式。结果表明,运动位错速度以及夹杂对于电-磁-弹性场具有很大影响。本文退化结果与前人的结果完全吻合。

| Abstract: | The mechanical and electromagnetic fields excited by a moving screw dislocation near a cylindrical rigid inclusion are investigated by complex variable method.The expressions of displacement,strains and stresses,electric fields and displacements,magnetic induction and field are derived explicitly.The results show that the velocity of moving dislocation and inclusion has significant effect on the electro-magneto-elastic fields.The present solutions contain previously known results as the special cases. |
