DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/120/">S
 train gradient plasticity and multi-well potentials</a>\nby Stefano Almi (
 University of Naples) as part of Nečas Seminar on Continuum Mechanics\n\n
 Lecture held in Room K3\,  Faculty of Mathematics and Physics\, Charles Un
 iversity\, Sokolovská 83  Prague 8..\n\nAbstract\nI will present a strain
 -gradient plasticity model obtained as\n$\\Gamma$-limit of a nonlinear fin
 ite dislocation model characterised by\na multiple-well potential and a si
 ngular perturbation term accounting\nfor the divergence of the strain fiel
 d. The analysis builds upon a new\nquantitative rigidity estimate for inco
 mpatible fields in presence of a\nmultiwell elastic energy\, showing that 
 the $L^{1^{*}}$-distance of a\nstrain field from a single well is controll
 ed in terms of the\n$L^{1^{*}}$-distance from a finite set of wells\, of c
 url $\\beta$\, and\nof ${\\rm div} \\beta$. This is a joint work with Dari
 o Reggiani (Scuola\nSuperiore Meridionale) and Francesco Solombrino (Unive
 rsity of Naples\nFederico II).\n
