Propagation of Transient Torsional Wave in a Transversely Isotropic Cylinder

利用分离变量和Laplace变换的方法研究了冲击扭转作用下半无限长横观各向同性圆柱体中应力波传播问题．计算结果表明：随着材料各向异性性质的增强，圆柱体中复杂应力分布范围增大．

The problem of elastic waves propagation in a transversely isotropic cylinder isinvestigated when a torque is suddenly applied to its end surface by means of the methods of theseparation variables and the Laplace transformation. It is shown that the influential range of thetwo-dimensional effect in the transversely isotropic cylinder becomes large as material anisotropy isstrong.
