An energy-based fracture model for multiple crack-branching, or crack-tip shattering, has been proposed and formulized for the Mode-I crack-tip condition in isotropic solids. An analytical solution of the energy release rate for multiple crack-branching from a Mode-I crack tip has been established. The cracking angles have also been analytically derived. It shows that the Griffith's theorem and conservation law can be applied to both the conventional Mode I crack extension and multiple crack-branching. The multiple crack-branching phenomena predicted by the present model are in good agreement with the experimental observations reported in the literature. (C) 2013 Elsevier Ltd. All rights reserved.
