摘要:
In this paper, the dispersion properties of elastic waves in the layered piezoelectric/piezomagnetic (PPC) hollow cylinder are investigated. The axisymmetric formulation is based on the Scaled Boundary Finite Element method. High-order elements are utilized for the discretization. We develop the mode sorting method to distinguish modes based on the reciprocity relation of the magneto-electro-elastic media. The dispersion relationship and wave structures of various layered PPC hollow cylinders are presented. Besides, we discuss impacts of the stacking sequence and radius-thickness ratio on the dispersive behavior and discover the frequency deletion of longitudinal modes. (C) 2015 Elsevier Ltd.
