Abstract
The analysis of transient linear elastic waves in Ref. [J. Acoust. Soc. Am. 94, 172–184 (1993)] is extended to 2-D axisymmetric finite layered periodic and weakly coupled media. Two essential features distinguishing 2-D propagation are flexure and increased dispersion. To allow separation of z and r eigenproblems, a boundary condition that approximates simple supports is adopted that yields nonorthogonal eigenfunctions in the modal analysis.
