Martedì 25 Ottobre 2016, alle ore 15 precise, presso la sala conferenze
dell’IMATI-CNR di Pavia, il

Prof. Gilles Francfort, Université Paris-Nord,

terrà un seminario dal titolo:

PERIODIC HOMOGENIZATION IN LINEAR ELASTICITY

nell'ambito del Seminario di Matematica Applicata (IMATI-CNR e
Dipartimento di Matematica, Pavia).

Al termine della conferenza sarà organizzato un piccolo rinfresco.

Abstract.

In 1993, Giuseppe Geymonat, Stefan Müller and Nicolas Triantafyllidis
demonstrated that, in the setting of linearized elasticity, a
Gamma-convergence result holds for highly oscillating sequences of
elastic energies whose functional coercivity constant over the whole
space is zero while the corresponding coercivity constant on the torus
remains positive. We find sufficient conditions for such a situation
to occur through a rigorous revisiting of a laminate construction
given by Gutierrez in 1999. We further demonstrate that isotropy
prohibits such an occurrence. The results should apply to both the
periodic and the stochastic setting. They were obtained in part with
Marc Briane (Rennes), and in part with Antoine Gloria (Brussels).
