[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 …

The Mumford–Shah variational model for image segmentation: An overview of the theory, implementation and use

A Vitti - ISPRS journal of photogrammetry and remote sensing, 2012 - Elsevier
Image segmentation is a hot topic of research given its applicability as a pre-processing
technique in many image understanding applications. This paper describes the Mumford …

[HTML][HTML] Fragmentation of inflated elastic brittle rings: Emergence of the quasi-equidistant spacing of cracks

S Michel, AA Sipos - Journal of the Mechanics and Physics of Solids, 2023 - Elsevier
The order of appearance and the position of meridional cracks in brittle domes is a delicate
question of mechanics. This paper investigates a dimension-reduced model, a pressurized …

Asymptotic analysis of Ambrosio--Tortorelli energies in linearized elasticity

M Focardi, F Iurlano - SIAM Journal on Mathematical Analysis, 2014 - SIAM
