Dynamic fracture mechanics analysis for composite material with material non-homogeneity in thickness direction

摘要

The problem considered here is the response of a non-homogeneous composite material containing some cracks subjected to dynamic loading. It is assumed that the composite material is or- thotropic and all material properties depend only on the coordinate y (along the thickness direcion). In the analysis, the elastic region is divided into a number of plies of infinite length. The material properties are taken to be constants for each ply. By utilizing the Laplace transform and Fourier transform technique, the general solutions for plies are derived.
