Lamb's Problem for an Impulsive Line Load on a Laminated Composite.

Abstract

The effective stiffness theory developed by Sun, Achenbach, and Herrmann is used to model a periodically laminated linearly elastic half space that is subjected to an impulsively applied line load. The laminations are parallel to the free surface. An approximate solution is constructed by approximating formal solutions (inversion integrals) near saddle points for low frequency and large distance from the source. Contributions include the responses of the body waves as well as the head and Rayleigh waves. Numerical results are presented in order to illustrate the differences between the dispersive and nondispersive solutions. (Author)
