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 …

[图书][B] Gamma-convergence for Beginners

A Braides - 2002 - books.google.com
The theory of Gamma-convergence is commonly recognized as an ideal and flexible tool for
the description of the asymptotic behaviour of variational problems. Its applications range …

A handbook of Г-convergence

A Braides - Handbook of Differential Equations: stationary partial …, 2006 - Elsevier
Publisher Summary This chapter discusses the main properties of Γ-convergence, in
particular those that are useful in the actual computation of Γ-limits. For some classes of …

[HTML][HTML] Phase field approximation of cohesive fracture models

S Conti, M Focardi, F Iurlano - Annales de l'Institut Henri Poincaré C …, 2016 - Elsevier
We obtain a cohesive fracture model as Γ-limit, as ε→ 0, of scalar damage models in which
the elastic coefficient is computed from the damage variable v through a function f ε of the …

Variational convergence of the Scharfetter–Gummel scheme to the aggregation-diffusion equation and vanishing diffusion limit

A Hraivoronska, A Schlichting, O Tse - Numerische Mathematik, 2024 - Springer
In this paper, we explore the convergence of the semi-discrete Scharfetter–Gummel scheme
for the aggregation-diffusion equation using a variational approach. Our investigation …

[图书][B] Discrete variational problems with interfaces

R Alicandro, A Braides, M Cicalese, M Solci - 2023 - books.google.com
Many materials can be modeled either as discrete systems or as continua, depending on the
scale. At intermediate scales it is necessary to understand the transition from discrete to …

A variational model for fracture and debonding of thin films under in-plane loadings

AAL Baldelli, JF Babadjian, B Bourdin, D Henao… - Journal of the …, 2014 - Elsevier
We study fracture and debonding of a thin stiff film bonded to a rigid substrate through a thin
compliant layer, introducing a two-dimensional variational fracture model in brittle elasticity …

Integral Representation for Functionals Defined on SBDp in Dimension Two

S Conti, M Focardi, F Iurlano - Archive for Rational Mechanics and …, 2017 - Springer
We prove an integral representation result for functionals with growth conditions which give
coercivity on the space SBD^ p (Ω) SBD p (Ω), for Ω ⊂ R^ 2 Ω⊂ R 2, which is a bounded …

Relaxation of convex functionals: the gap problem

E Acerbi, G Bouchitté, I Fonseca - Annales de l'Institut Henri Poincaré C …, 2003 - Elsevier
It is shown that the relaxed energy [Formula: see text] admits the representation [Formula:
see text] where f is a convex, Carathéodory integrand satisfying a nonstandard “α–β” growth …

A Γ-convergence approach to stability of unilateral minimality properties in fracture mechanics and applications

A Giacomini, M Ponsiglione - Archive for rational mechanics and analysis, 2006 - Springer
We prove a stability result for a large class of unilateral minimality properties which arise
naturally in the theory of crack propagation proposed by Francfort & Marigo in [14]. Then we …
