Fund Project: This research has been partially supported from the grants 16-03823S "Homogenization and multi-scale computational modelling of flow and nonlinear interactions in porous smart structures" and 14-15264S "Experimentally justified multiscale modelling of shape memory alloys" of Czech Science Foundation, and from the institutional support RVO:61388998 (ČR).

The model of brittle cracks in elastic solids at small strains is approximated by the Ambrosio-Tortorelli functional and then extended into evolution situation to an evolutionary system, involving viscoelasticity, inertia, heat transfer, and coupling with Cahn-Hilliard-type diffusion of a fluid due to Fick's or Darcy's laws. Damage resulting from the approximated crack model is considered rate independent. The fractional-step Crank-Nicolson-type time discretisation is devised to decouple the system in a way so that the energy is conserved even in the discrete scheme. The numerical stability of such a scheme is shown, and also convergence towards suitably defined weak solutions. Various generalizations involving plasticity, healing in damage, or phase transformation are mentioned, too.

Keywords: Viscoelasticity at small strains, inertia, damage, crack, AmbrosioTortorelli approximation, Cahn-Hilliard equation, Fick and Darcy flow, fractional step splitting, Crank-Nicolson formula, convergence, existence of weak solutions.
