Phase field approximation of cohesive fracture models

We obtain a cohesive fracture model as Γ-limit, as null null null e null → null 0 null null , of scalar damage models in which the elastic coefficient is computed from the damage variable v through a function null null null null null f null null null e null null null null null of the form null null null null null f null null null e null null null ( null v null ) null = null min null ⁡ null { null 1 null , null null null e null null null null 1...
