Abstract

The transient response of functionally graded materials of arbitrary properties with a crack vertical to the free surfaces is analyzed theoretically. The impact loading condition is considered. Based on the piecewise-exponential model (PE model), a new analytic method is developed. The dynamic stress intensity factors (DSIFs) are calculated by using Laplace and Fourier integral transforms, singular integral equation methods, the theory of residues and the Laplace numerical inversion technique. Some representative samples with different kinds of nonhomogeneous properties are analyzed and the corresponding DSIFs are presented. It is shown that the properties varying forms have greatly influences on the DSIFs.
