Abstract:
In this work, we present the model for the study of rock mechanics, where we introduce the concept of damage. following the ideas of J.J. Marigo et al, we consider a variational formulation for study the dynamics of the rocks damage and the fracture mechanics. We will discuss the optimality conditions of the problem and present some numerical results. Finally we will present some applications to underground mining.
