Abstract

The present study is concerned with the effect of rotation on the propagation of plane waves in a transversely isotropic medium in the context of thermoelasticity theory of GN theory of types II and III. After solving the governing equations, three waves propagating in the medium are obtained. The fastest among them is a quasilongitudinal wave. The slowest of them is a thermal wave. The remaining is called quasitransverse wave. The prefix “quasi” refers to their polarizations being nearly, but not exactly, parallel or perpendicular to the direction of propagation. The polarizations of these three waves are not mutually orthogonal. After imposing the appropriate boundary conditions, the amplitudes of reflection coefficients have been obtained. Numerically simulated results have been plotted graphically with respect to frequency to evince the effect of rotation and anisotropy.
旋转对横向各向同性热弹性半空间中波传播的影响
本文从热弹性理论的第二类和第三类GN理论出发,研究了旋转对平面波在横向各向同性介质中传播的影响。在求解控制方程后,得到了在介质中传播的三种波。其中最快的是准纵波。其中最慢的是热波。剩下的被称为准横波。前缀“准”是指它们的极化接近,但不完全平行或垂直于传播方向。这三个波的偏振不是互相正交的。在施加适当的边界条件后,得到了反射系数的振幅。数值模拟结果与频率有关,以显示旋转和各向异性的影响。
