| Abstract | This paper summarizes some results on stress intensity factor (SIF) histories for a 3D crack moving steadily and unsteadily. In the first part,elastodynamic SIF for a unbounded solid containing a planar crack that propagates at a constant velocity under 3D time-independent loading is considered. The solutions of a general loading are expressed out in term of superposition integral based on the fundamental solution procedure. In the last part,using the form of Willis et al (1995) of dynamic mode I weight function for a moving crack,the propagation of a planar crack with a perturbation from straightness of the edge and the associated perturbation of the SIF is investigated. The result snows that the oscillatory crack tip motion through brittle,locally heterogeneous materials could be the basis for careful recent measurements by Gross et al(1993). |
