discipline of engineering fracture mechanics. This review focuses on two promising …

Crack nucleation in variational phase-field models of brittle fracture

E Tanné, T Li, B Bourdin, JJ Marigo… - Journal of the Mechanics …, 2018 - Elsevier
Phase-field models, sometimes referred to as gradient damage or smeared crack models,
are widely used methods for the numerical simulation of crack propagation in brittle …

Saddle-to-saddle dynamics in diagonal linear networks

S Pesme, N Flammarion - Advances in Neural Information …, 2023 - proceedings.neurips.cc
In this paper we fully describe the trajectory of gradient flow over $2 $-layer diagonal linear
networks for the regression setting in the limit of vanishing initialisation. We show that the …

Rate-independent systems

A Mielke, T Roubíček - Applied Mathematical Sciences, 2015 - Springer
Our work on rate-independent systems was stimulated by our search for evolutionary
material models for shape-memory alloys that are flexible enough to encompass nonlinear …

The variational approach to fracture

B Bourdin, GA Francfort, JJ Marigo - Journal of elasticity, 2008 - Springer
At the risk of being unfair, we credit first and foremost AA Griffith for developing the field of
brittle fracture. His views were that cracks are the macroscopic manifestation of putative …

Gradient damage models and their use to approximate brittle fracture

K Pham, H Amor, JJ Marigo… - International Journal of …, 2011 - journals.sagepub.com
In its numerical implementation, the variational approach to brittle fracture approximates the
crack evolution in an elastic solid through the use of gradient damage models. In this article …

Gradient damage models coupled with plasticity: variational formulation and main properties

R Alessi, JJ Marigo, S Vidoli - Mechanics of Materials, 2015 - Elsevier
A variational formulation is proposed for a family of elastic–plastic–damage models within
the framework of rate-independent materials. That consists first in defining the total energy …
