The boundary contour method for magneto-electro-elastic media with quadratic boundary elements

摘要

This paper presents a development of the boundary contour method (BCM) for magneto-electro-elastic media. First, the divergence-free of the integrand of the magneto-electro -elastic boundary element is proved. Second, the boundary contour method formulations are obtained by introducing quadratic shape functions and Green's functions (Ding, H.J., Jiang, A.M., 2004. A boundary integral formulation and solution for 2D problems in magneto-electro-elastic media. Computers and Structures, 82 (20-21), 1599-1607] for magneto-electro-elastic media and using the rigid body motion solution to regularize the BCM and avoid computation of the corner tensor. The BCM is applied to the problem of magneto-electro-elastic media. Finally, numerical solutions for illustrative examples are compared with exact ones The numerical results of the BCM coincide very well with the exact solution, and the feasibility and efficiency of the method are verified.
