给出了超声波在纤维增强复合材料中传播的计算结果，其中纤维增强是单向的。同时考虑了弹性各向同性纤维和各向异性纤维。将传播方向取为与纤维长度垂直的方向，得到了纵波速度和横波速度与复合孔洞和纤维体积分数的函数关系式。计算结果显示了合理的行为，并与现有的实验数据进行了比较，显示出良好的一致性。
Calculated results are presented for ultrasonic wave propagation in fiber‐reinforced composite material containing voids, where the fiber reinforcement is unidirectional. Both elastically isotropic and anisotropic fibers are considered. The propagation direction is taken as normal to the fiber length and expressions are obtained for the longitudinal‐ and shear‐wave velocities as a function of composite void and fiber volume fraction. The results exhibit reasonable behavior and a comparison of calculated data and such experimental data as are available shows fair agreement.
