THE CONSERVATION LAWSAND PATH-INDEPENDENT INTEGRALS FOR PIEZOELECTRIC MEDIA
-
摘要: 借鉴分析动力学中的Ｊａｃｏｂｉ积分和循环积分概念，以及电磁场理论中的能量矩概念，导出了压电介质在静态场中的守恒方程形式，由这些守恒方程即可得到在位错、断裂力学和其他缺陷理论中应用广泛的路径无关积分。Abstract: Motivated by concepts of Jacobi integral and cyclic integral in analytical me-chanics and energy-momentum tensor in electro-magntic field,the conservation laws forpiezoelectric materials were derived, from which the path independent integrals can be ob-tained.
