About the Mathematical Modeling of Irreversibility Problems
We are concerned with the modeling of irreversible behaviors in Solid Mechanics and the numerical solution of the associated free boundary problem. A general enough framework is presented which allows us to represent typical stress/strain diagrams in the study of damage processes. We state some mathematical results in order to prove the coherence of the model with respect to the given diagrams. Theoretic tools are discussed for the solution of the corresponding discrete finite element problem.
