| Abstract: | Discontinuous waves penetrating the interfaces of transversely isotropic elastic media are studied using the ray-path method. The cases where such waves interact with curvilinear reflectors and with biconvex and biconcave lenses are considered. It is shown that discontinuous waves can focus or scatter depending on the physical properties and sequence of the media under consideration.Translated from Prikladnaya Mekhanika, Vol. 40, No. 10, pp. 98–106, October 2004. |
