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…
Systematic design of compliant morphing structures: a phase-field approach
Jamal Shabani, Kaushik Bhattacharya, Blaise Bourdin
We investigate the systematic design of compliant morphing structures composed of materials reacting to an external stimulus. We add a perimeter penalty term to ensure existence of…
A DG/CR discretization for the variational phase-field approach to fracture
Frederic Marazzato, Blaise Bourdin
Variational phase-field models of fracture are widely used to simulate nucleation and propagation of cracks in brittle materials. They are based on the approximation of the solutio…
Fracture Diodes: Directional asymmetry of fracture toughness
N. R. Brodnik, S. Brach, C. M. Long +4
Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the re…
Optimal Design of Responsive Structures
Andrew Akerson, Blaise Bourdin, Kaushik Bhattacharya
With recent advances in both responsive materials and fabrication techniques it is now possible to construct integrated functional structures, composed of both structural and activ…
Phase-field study of crack nucleation and propagation in elastic - perfectly plastic bodies
Stella Brach, Erwan Tanné, Blaise Bourdin +1
Crack initiation and propagation in elastic - perfectly plastic bodies is studied in a phase-field or variational gradient damage formulation. A rate-independent formulation that n…
On the asymptotic derivation of Winkler-type energies from 3D elasticity
Andrés A León Baldelli, Blaise Bourdin
We show how bilateral, linear, elastic foundations (i.e. Winkler foundations) often regarded as heuristic, phenomenological models, emerge asymptotically from standard, linear, thr…
