在发展超声检测复合材料厚壁空心圆柱体的技术中，研究了纵谐波在横观各向同性壳体中的传播。得到了满足应力-应变内、外圆柱边界条件的特征方程的精确形式，即波长、圆柱半径和材料常数。对于一些典型的样品材料，计算了不同圆柱半径的宽波长范围内基模的相速度。第二振动模式的壳波速度也被提出。比较了壳波速度和板波速度。复合壳体的波速传播比各向同性壳体的波速传播宽得多。
The propagation of a longitudinal harmonic wave in a transversely isotropic shell has been investigated in the development of ultrasonic techniques for thick hollow composite cylinders. The characteristic equation for satisfying the stress-fee inner and outer cylindrical boundaries has been obtained in an exact form in terms of the wavelength, the cylinder radii and the material constants. The phase velocity of the fundamental mode is calculated for a wide range of the wavelength for various cylinder radii for some typical sample materials. The shell wave speeds for the second mode of vibration are also presented. Comparisons are made between shell wave speeds and plate wave speeds. The spread of the wave speeds for the composite shells is shown to be much wider than that for an isotropic shell.
