Abstract
A computational procedure for multiple scattering of elastic waves in unidirectional fiber-reinforced composite materials is presented. The present study deals with the time-harmonic propagation of the P wave (longitudinal wave) and the SV wave (shear wave polarized vertical to the fibers). The exciting and scattered fields for each fiber are expressed by the eigenfunction expansion, and a collocation method is used to determine the expansion coefficients numerically. With this procedure, the P and SV wave scattering and propagation in the unidirectional SiC/Ti-alloy composite are analyzed for a square arrangement of the fibers. This analysis enables to simulate multiple scattering considering mode conversion.
