Abstract

Controlling the crack propagation along a desired path has important applications in fabrication. We propose a method for extending a crack along a desired trajectory by controlling the direction of an applied external point force. Examples of crack propagation along arc and sinusoidal paths are illustrated, and verified through numerical simulations based on the extended finite element method (XFEM). © 2009 Elsevier Ltd.
