研究了沿各向同性中空圆柱周向传播的时谐剪切水平(SH)波。解析地推导了色散方程以及壁厚方向的位移场和应力场。与平板中的SH波相比较，给出了平板模型在圆周方向上逼近管道的定量指标，以用于缺陷表征。这项工作对于启动用于管道检测的三维波散射工作也是至关重要的。(C)2004年美国声学学会。
Guided time-harmonic shear horizontal (SH) waves propagating in the circumferential direction of an isotropic hollow cylinder are studied. The dispersion equation as well as the displacement and stress field across the wall thickness is derived analytically. Compared with the SH waves in a plate, a quantitative guideline of how well a plate model can approximate a pipe in the circumferential direction is given for defect characterization purpose. The work is also crucial for initiating work efforts on three-dimensional wave scattering for pipeline inspection. (C) 2004 Acoustical Society of America.
