Title: Mathematical models in fracture mechanics

Abstract: We present an overview on the variational approach to quasistatic evolution problems in fracture mechanics. We focus on the most recent results on brittle cracks in hyperelastic bodies, in the context of finite elasticity. In these models the solutions are obtained through an approximation procedure by time discretization and the approximate solutions are obtained by solving suitable incremental minimum problems.

BIOGRAPHY: Gianni Dal Maso was student of Ennio De Giorgi at the Scuola Normale in Pisa from 1975 to 1981. After a short period (1982-1985) at the University of Udine, he moved to SISSA in Trieste, where he became full professor of Calculus of Variations in 1987 and then head of the Sector of Functional Analysis and Applications (1993-1998 and 2001-2010). Since 2010 he is Deputy Director of SISSA. His research activity is devoted to the calculus of variations, in particular to semicontinuity and relaxation problems, Gamma-convergence, and, more recently, to free discontinuity problems and applications to mechanics. He is corresponding member of the Istituto Veneto di Scienze, Lettere ed Arti (since 2012) and of the Accademia Nazionale dei Lincei (since 2014). So far he has been advisor of 34 SISSA Ph.D. students
