The antiferromagnetic XY model on the triangular lattice: chirality transitions at the surface scaling

Annika Bach, Marco Cicalese, Leonard Kreutz +1

We study the discrete-to-continuum variational limit of the antiferromagnetic XY model on the two-dimensional triangular lattice. The system is fully frustrated and displays two fa…

A lower semicontinuity result for linearised elasto-plasticity coupled with damage in ,

Vito Crismale, Gianluca Orlando

We prove the lower semicontinuity of functionals of the form \[ \int \limits_Ω\! V(α) \, \mathrm{d} |\mathrm{E} u| \, , \] with respect to the weak converge of in ,…

Variational analysis of a two-dimensional frustrated spin system: emergence and rigidity of chirality transitions

Marco Cicalese, Marwin Forster, Gianluca Orlando

We study the discrete-to-continuum variational limit of the - spin model on the square lattice in the vicinity of the helimagnet/ferromagnet transition point as the l…

Fatigue effects in elastic materials with variational damage models: A vanishing viscosity approach

Roberto Alessi, Vito Crismale, Gianluca Orlando

We study the existence of quasistatic evolutions for a family of gradient damage models which take into account fatigue, that is the process of weakening in a material due to repea…

Cohesive fracture with irreversibility: quasistatic evolution for a model subject to fatigue

Vito Crismale, Giuliano Lazzaroni, Gianluca Orlando

In this paper we prove the existence of quasistatic evolutions for a cohesive fracture on a prescribed crack surface, in small-strain antiplane elasticity. The main feature of the…

A Reshetnyak-type lower semicontinuity result for linearised elasto-plasticity coupled with damage in

Vito Crismale, Gianluca Orlando

In this paper we prove a lower semicontinuity result of Reshetnyak type for a class of functionals which appear in models for small-strain elasto-plasticity coupled with damage. To…
