Abstract:

Progress in the prediction of crack initiation and propagation requires understanding its interaction with localized perturbations. Here we investigate the intrinsic instabilities of crack fronts that nucleate from heterogeneities and create surface structure. By visualizing the crack front as it forms the fracture surface we show a direct quantitative relationship between crack front deformation and surface structure.
