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.
Journal ArticleDOI
The issues of the uniqueness and the stability of the homogeneous response in uniaxial tests with gradient damage models
TL;DR: In this paper, a variational approach based on the principles of irreversibility, stability and energy balance is proposed to identify the two constitutive functions of a gradient damage model.
Journal ArticleDOI
An overview of the modelling of fracture by gradient damage models
TL;DR: In this article, a variational approach to fracture is used to describe all the process of degradation of a body including the nucleation of cracks and their propagation, and the formulation of the damage evolution problem is then based on the concepts of irreversibility, stability and energy balance.
Journal ArticleDOI
Transient computational homogenization for heterogeneous materials under dynamic excitation
TL;DR: In this paper, a transient computational homogenization approach is proposed for modeling the evolution in space and time of materials with non-steady state microstructure, such as metamaterials.
Journal ArticleDOI
From the onset of damage to rupture: construction of responses with damage localization for a general class of gradient damage models
Kim Pham,Jean-Jacques Marigo +1 more
TL;DR: In this paper, a non-homogeneous solution for the traction problem of an elastic damaging bar is proposed, which is applicable for a wide range of brittle materials. But it is only applicable to sufficiently long elastic damaging bars.
