Propagation of shock waves in anisotropic composite plates

Abstract

Shock fronts in laminated plates subjected to impact loadings are in-vestigated by the ray theory. The kinematic conditions of compatibility and the dynamical conditions on the wave fronts are derived. The propaga-tion velocity, the expression for the position of the wave front, and the ray geometry are presented. From the ray geometry, the directions of propa-gation along which the wave front decays or grows more rapidly are found. Numerical solutions for cross-ply laminates are discussed
