Homogenization of the Peierls-Nabarro model for dislocation dynamics
Stefania Patrizi · 2014
Abstract. This paper is concerned with a result of homogenization of an integro-differential equation describing dislocation dynamics. Our model involves both an anisotropic Lévy operator of order 1 and a potential depending periodically on u/. The limit equa-tion is a non-local Hamilton-Jacobi equation, which is an effective plastic law for densities of dislocations moving in a single slip plane. 1.
