Abstract

Dynamic stress intensity factor (DSIF) is an important fracture parameter in understanding and predicting dynamic fracture behavior of a cracked body. To evaluate DSIFs for functionally graded materials (FGMs), the interaction integral originally proposed to evaluate SIFs for a static homogeneous medium is extended to incorporate dynamic effects and material nonhomogeneity, and is implemented in conjunction with the finite element method (FEM). To verify numerical implementations and to explore various dynamic fracture behaviors, both homogeneous and nonhomogeneous cracked bodies under dynamic loading are employed.
