Irreversibility and alternate minimization in phase field fracture: a viscosity approach
Stefano Almi
This work is devoted to the analysis of convergence of an alternate (staggered) minimization algorithm in the framework of phase field models of fracture. The energy of the system…

Crack growth by vanishing viscosity in planar elasticity
Stefano Almi, Giuliano Lazzaroni, Ilaria Lucardesi
We show the existence of quasistatic evolutions in a fracture model for brittle materials by a vanishing viscosity approach, in the setting of planar linearized elasticity. The cra…

Analysis of staggered evolutions for nonlinear energies in phase field fracture
Stefano Almi, Matteo Negri
We consider a class of separately convex phase field energies employed in fracture mechanics, featuring non-interpenetration and a general softening behavior. We analyze the time-d…
