碩士 === 國立成功大學 === 航空太空工程學系 === 106 === On the basis of the convenient and regular features that extended Stroh-like formalism for coupled-stretching-bending anisotropic elasticity can be extended from the elastic material to the piezoelectric and magneto-electro-elastic materials by expanding the related matrix dimension. Through the boundary element method, the fundamental solution for the magneto-electro-elastic material infinite plate can be found, the elastic, piezoelectric and magneto-electro-elastic materials can also employ the same fundamental solution without finding solutions individually at the same time. Because of the most commercial software only can solve elastic composite laminates coupled-stretching-bending problem, our research group develop the structure engineering analysis software, AEPH, which can apply boundary element method to solve the magneto-electro-elastic material coupled-stretching-bending problem. To verify the correctness of this method, the elastic, piezoelectric and magneto-electro-elastic symmetric/unsymmetric plate under the axial distributed tension or out of plane bending, are presented and compared with the commercial software, ANSYS, Stroh analytical solution and two dimension boundary element method.
