TY - EJOU AU - Wei, Jianping AU - Su, Xianyue TI - Steady-state Response of the Wave Propagation in a Magneto-Electro-Elastic Square Column T2 - Computer Modeling in Engineering \& Sciences PY - 2008 VL - 37 IS - 1 SN - 1526-1506 AB - The steady-state response of the wave propagation in a magneto-electro-elastic square column (MEESC) was studied. Some new characteristics were discovered: the guided waves are classified in the forms of the Quasi-P, Quasi-SV and Quasi-SH waves and ordered by the standing wave number, and the three type guided waves are corresponding to the extension, twist and shear modes of the body vibration; the induced electric and magnetic fields can be aroused by the propagating stress wave. We proposed a self-adjoint method, by which the guided-wave restriction condition was derived. After finding the corresponding orthogonal sets, the analytic dispersion equation was obtained. In the end, an example was presented. The dispersive spectrum, the group velocity curve and the steady-state response curve of MEESC were plotted.
