2-DIMENSIONAL STRESS WAVE-PROPAGATION IN A TRANSVERSELY ISOTROPIC CYLINDER

A numerical analysis of two-dimensional wave propagation in a transver sely isotropic cylinder is presented. The equations governing the dyna mic deformation are solved by means of the method of numerical integra tion along bicharacteristics. Numerical simulations of elastic wave pr opagation in a fiber-reinforced composite cylinder due to impact load are performed. A numerical solution for the special case of the transv ersely isotropic cylinder is shown to he ill acceptable agreement with impact experiment results. The stability and convergence of the prese nt method are evaluated by checking the relative error in the total en ergy of the system.
