A continuum phase field model for fracture
Charlotte Kuhn,Ralf Müller +1 more
TL;DR: In this article, a phase field model based on a regularized version of the variational formulation of brittle fracture is introduced, and the influences of the regularization parameter that controls the interface width between broken and undamaged material and of the mobility constant of the evolution equation are studied in finite element simulations.
A Continuum Phase Field Model for Fracture
Ralf Müller,Charlotte Kuhn +1 more
TL;DR: A variational free-discontinuity formulation of brittle fracture was given by Francfort and Marigo as discussed by the authors, where the total energy is minimized with respect to the crackgeometry and the displacement field simultaneously.
Journal ArticleDOI
On degradation functions in phase field fracture models
TL;DR: In this article, the authors discuss the potential of alternative degradation functions in the context of crack nucleation and propagation, which is not desirable when modeling brittle materials, as the degradation function frequently found in the literature yields a pronounced softening behavior before the onset of fracture.
Journal ArticleDOI
Phase field approximation of dynamic brittle fracture
TL;DR: In this paper, an extension of the quasi-static phase field model for fracture from Kuhn and Muller (Eng Fract Mech 77(18):3625---3634, 2010) to the dynamic case is presented.
