title: Unsteady crack motion and branching in a phase-field model of brittle fracture.
abstract: Crack propagation is studied numerically using a continuum phase-field approach to mode III brittle fracture. The results shed light on the physics that controls the speed of accelerating cracks and the characteristic branching instability at a fraction of the wave speed.
