Sensitivity analysis is applied to a regularised non-local ductile damage model. A variational approach utilised derive the analytical gradients of different objectives with respect either geometrical material parameters. Due definition model, enhanced algorithmic treatments are necessary capture its history dependent nature within sensitivity computation. The gradient information parameters us...

We consider a model for the evolution of damage in elastic materials originally proposed by Michel Frémond. For corresponding PDE system, we prove existence and uniqueness local time strong solution. The main novelty our result stands fact that, differently from previous contributions, assume no occurrence any type regularising terms.
