Crack front dynamics
Abstract eng: Nominal toughness of materials is determined by structure and material composition, but actual toughness is strongly affected by macroscopic three-dimensional instabilities of cracks. We will present novel experiments in brittle gels, probing the dynamics of crack fronts as the fronts become unstable. By comparing the surface area created by unstable cracks to local velocity and curvature of the propagating crack fronts that created the fracture surface, we test the validity of planar front perturbation theory to bulk 3D fracture.
