Strength-degradation phase-field regularization of cohesive fracture: the antiplane case
Blaise Bourdin, Corrado Maurini
Phase-field approaches to fracture, initially designed as regularization of the Griffith model of brittle fracture, are now commonly viewed as gradient-damage models whose regulari…

A variational approach to fracture incorporating any convex strength criterion
Blaise Bourdin, Jean-Jacques Marigo, Corrado Maurini +1
We propose a variational phase-field model of fracture capable of accounting for arbitrary closed convex strength domains. Unlike traditional models based on Ambrosio and Tortorell…

Grain-size dependence of plastic-brittle transgranular fracture
Jean-Michel Scherer, Mythreyi Ramesh, Blaise Bourdin +1
The role of grain size in determining fracture toughness in metals is incompletely understood with apparently contradictory experimental observations. We study this grain-size depe…
