Abstract:

We describe an existence result for quasistatic evolutions of cracks in antiplane elasticity obtained in Lazzaroni-Toader, M3AS 2011, by a vanishing viscosity approach, with free (but regular enough) crack path. We underline in particular the motivations for the choice of the class of admissible cracks and of the dissipation potential. Moreover, we extend the result to a model with applied forces depending on time.
