Séminaire Modèles et Algorithmes Déterministes: EDP-MOISE-MGMI

Dislocations are point defects appearing in crystals, as a  
response to plastic deformations. In this talk I propose a location problem for screw dislocations, in presence of a Dirichlet boundary condition. The study is carried out  with techniques of Gamma-convergence and PDEs, in the framework of the so-called "core-radius approach".
The talk is based on recents results obtained in collaboration with M.  
Morandotti, R. Scala, and D. Zucco.
