Tuesday, 27 November 2018, 3 p.m. (sharp),

Dr. Vito Crisme, CMAP, École Polytechnique, Parigi.

at the conference room of IMATI-CNR in Pavia, will give a lecture titled:

Minimisation and Ambrosio-Tortorelli approximation of the Griffith energy with Dirichlet boundary condition

as part of the Applied Mathematics Seminar (IMATI-CNR e Dipartimento di Matematica, Pavia).

At the end a refreshment will be organized.


Abstract. I will present recent works about the minimisation of the Griffith energy for brittle fracture, under Dirichlet boundary conditions. Together with Antonin Chambolle (CMAP, École Polytechnique) we have proven the existence of minimisers and a phase-field approximation à la Ambrosio-Tortorelli for the Griffith energy, generalising the corresponding results for the Mumford-Shah functional in image reconstruction.
