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.
