From damage to delamination via evolutionary Gamma-convergence in a rate-independent quasibrittle regime
Giovanna Bonfanti, Elisa Davoli, Riccarda Rossi +1
We analyze via Evolutionary Gamma-convergence a stratified composite structure consisting of a thin adhesive layer with vanishing thickness and undergoing rate-independent damage,…
On De Giorgi's lemma for variational interpolants in metric and Banach spaces
Alexander Mielke, Riccarda Rossi
Variational interpolants are an indispensable tool for the construction of gradient-flow solutions via the Minimizing Movement Scheme. The De Giorgi lemma provides the associated d…
A coupled rate-dependent/rate-independent system for adhesive contact in Kirchhoff-Love plates
Giovanna Bonfanti, Elisa Davoli, Riccarda Rossi
We perform a dimension reduction analysis for a coupled rate-dependent/rate-independent adhesive-contact model in the setting of visco-elastodynamic plates. We work with a weak sol…
Singular jump processes as generalized gradient flows
Jasper Hoeksema, Riccarda Rossi, Oliver Tse
We extend the generalized gradient-flow framework of Peletier, Rossi, Savaré, and Tse to singular jump processes on abstract metric spaces, moving beyond the translation-invariant…
Existence and weak-strong uniqueness for damage systems in viscoelasticity
Robert Lasarzik, Elisabetta Rocca, Riccarda Rossi
In this paper we investigate the existence of solutions and their weak-strong uniqueness property for a PDE system modelling damage in viscoelastic materials. In fact, we address t…
On the visco-plastic approximation of a rate-independent coupled elastoplastic damage model
Vito Crismale, Giuliano Lazzaroni, Riccarda Rossi
In this paper we study a rate-independent system for the propagation of damage and plasticity. To construct solutions we resort to approximation in terms of viscous evolutions, whe…
