Abstract:

We propose a time-space discretization of a general notion of quasistatic growth of brittle fractures in elastic bodies proposed in 13 by G. Dal Maso, G.A. Francfort, and R. Toader, which takes into account body forces and surface loads. We employ adaptive triangulations and prove convergence results for the total, elastic and surface energies. In the case in which the elastic energy is strictly convex, we prove also a convergence result for the deformations.

Keywords: variational models, Crack propagation, energy minimization, finite elements, brittle fractures, quasistatic growth
