In particular, this framework is relevant in the context of fracture and damage mechanics. **Irreversible Evolution of Damage** -Let $y=(\alpha, u)$ be an admissible state of a brittle system where $\alpha: \Omega \mapsto [0, 1]$ is a smooth damage field which identifies cracks (where $\alpha =1$) and $u$ is a displacement field. Provided a material model (an energy) $E_\ell$, given a time horizon $T$, let's find a map $t \in [0, T]\mapsto y_t$ such that: damage is non-decreasing and the observed state $y_t$ is energy-minimal, among admissible variations. +Let $y=(\alpha, u)$ be an admissible state of a brittle system where $\alpha: \Omega \mapsto [0, 1]$ is a smooth damage field which identifies cracks (where $\alpha =1$) and $u$ is a displacement field.
