2. Modeling the behavior of materials in large deformations

In continuous damage mechanics, damage is quantified by the set of microcracks and cavities whose orientation is uniformly distributed in all directions. The variable D m ∊ [0, 1] associated with the direction m characterizing the state of material deterioration due to the accumulation and propagation of microcracks is given by :
