The transient response of a functionally graded strip with an embedded or edge crack perpendicular to the boundary is studied under an in‐plane impact load. By means of integral transform methods, the present problem is changed into a singular integral equation which can be solved numerically in the Laplace domain. It is found that the singular terms for the edge crack are different from those for the embedded crack. The influences of parameters such as the nonhomogeneity constant and the geometry parameters on the dynamic stress intensity factors (DSIFs) are studied.
