Journal ArticleDOI
Revisiting brittle fracture as an energy minimization problem
TL;DR: In this paper, a variational model of quasistatic crack evolution is proposed, which frees itself of the usual constraints of that theory : a preexisting crack and a well-defined crack path.
Journal ArticleDOI
Numerical experiments in revisited brittle fracture
TL;DR: The numerical implementation of the model of brittle fracture developed in Francfort and Marigo (1998) is presented in this paper, where various computational methods based on variational approximations of the original functional are proposed.

The Variational Approach to Fracture
TL;DR: In this article, a weak variational evolution is proposed for 1D traction on a fiber reinforced matrix, and a variational formulation for fatigue is presented, which is based on the soft belly of Griffith's formulation.
Journal ArticleDOI
Regularized formulation of the variational brittle fracture with unilateral contact: Numerical experiments
TL;DR: In this paper, a modified regularized formulation of the Ambrosio-Tortorelli type was proposed to avoid crack interpenetration and predicts asymmetric results in traction and in compression.
Journal ArticleDOI
Gradient Damage Models and Their Use to Approximate Brittle Fracture
TL;DR: In this paper, a variational approach to brittle fracture approximates the crack evolution in an elastic solid through the use of gradient damage models, and a stability criterion in terms of the positivity of the second derivative of the total energy under the unilateral constraint induced by the irreversibility of damage is introduced.
