The directional instability of moving cracks was studied within the context of the maximum dilatational energy density, or T-criterion. To make bifurcation predictions according to the T-criterion theory it suffices to consider only the singular stress field. In this paper the stress field for a non

β¦ Synopsis
Dynamic crack-branching was studied according to Det.-criterion of fracture. In this paper the stress field for a non-uniformly propagating crack under mode I deformation was adopted. Predictions concerning both the critical crack velocity and the bifurcation angle was given. According to Det-criterion, which was developed by the author, the crack propagates in the direction of the maximum value of the determinant of the stress tensor.

The phenomenon of directional instability of running cracks is studied by means of a "twincrack" model. The running single crack tip is simulated by a cloud of microcracks under the form of hackles with random lengths and orientations, which, finally, are reduced into a flat front with two dominant
Recent developments in numerical techniques for dynamic transient stress analysis have ensured that realistic models can now be employed in crack propagation studies. In this paper transient dynamic finite element solutions are undertaken for both double cantilever beam (DCB) and pipeline problems w
