“…Furthermore, there is rare research on three-dimensional body-wave propagating in a magneto-electro-elastic structure. Although some conclusions about SH wave [6][7][8] propagation through piezoelectric plate or magneto-electro-elastic materials were reported, they cannot reflect the whole feature we considered. In general, the Bessel-Fourier expansion method [9] and the Stroh method [10] can be applied in studying the body-wave problem of a magneto-electro-elastic structure.…”

This is a continued work in studying the wave propagation in a magneto-electroelastic square column (MEESC). Based on the analytic dispersive equation, group velocity equation and steady-state response obtained in our previous paper 'Steady-state response of the wave propagation in a magneto-electro-elastic square column' published in CME, the dynamical behavior of MEESC was studied in this paper. The unlimited column is an open system. The transientstate response in the open system subjected by arbitrary external fields was derived when the propagating wave pursuing method was introduced.

“…Here one can find monographs, 1-4 review articles ͑e.g., see the paper by Chimenti 5 with four hundred references͒, and numerous original publications. There are several different approaches to the problem: general theoretical studies, 6-13 explicit calculations, [14][15][16][17][18][19][20][21][22][23][24] and computer analysis. [25][26][27][28] Of course, this list is very incomplete ͑we recall approximately 400 references in Ref.…”

The dispersion spectra of SH guided waves are studied both analytically and numerically for two-layered plates with a plane of propagation being the plane of transverse isotropy. The boundary-value problems are considered for a plate with free, clamped, or clamped/free surfaces. It is noticed that formally the problem is very similar to that for symmetric and antisymmetric Lamb waves in a homogeneous plate. On this basis the Mindlin's approach of a bound grid is applied for an analysis. It is found that the studied spectra are characterized by the following specific features. They have two asymptotic levels c t1 and c t2 corresponding to the speeds of SH bulk waves in both layers. In the vicinity of the upper level ͑c t2 ͒ dispersion curves form a step-like pattern tending to c t2 in succession one by one with further going down to the lower asymptote c t1 . Over the level c t2 there is a zone, where dispersion curves have a wavy form similar to that in spectra of Lamb waves in homogeneous plates. It is shown that the families of dispersion branches related to the boundary conditions of free and clamped surfaces cross each other at the same types of nodes of Mindlin's grid as those for symmetric and antisymmetric Lamb waves in a free homogeneous plate. The tracing speed level v = v 0 is found where the appropriate families of dispersion curves cross each other beyond the nodes of Mindlin's grid. It is proved that the spectra of symmetric and antisymmetric SH guided waves in symmetric three-layered plates with free or clamped faces are described by the same four equations as for the studied two-layered plates with free, clamped, free/clamped or clamped/free surfaces.
