Abstract

The talk concerns crack initiation in a hyper-elastic body governed by a Griffith's type energy. In collaboration with Antonin Chambolle (Ecole Polytechnique, Paris) and Marcello Ponsiglione (Max Planck Institute, Leipzig) we prove that, during a loading process and in absence of strong singularities, the crack appears after a strictly positive time. On the contrary, in presence of a point x of strong singularity, a crack will depart from x at the initial time of loading and with zero velocity. We prove these facts for admissible cracks belonging to the large class of closed one dimensional sets with a finite number of connected components. [DOI: 10.1685/CSC06088] About DOI
