We discuss several elastic energies for nematic elastomers and their small strain
expansions both in the regime of large director rotations, and in the case that director …

We prove that a quasiconvex function W: Mn× n→[0,∞] which is finite on the set Σ={F: detF=
1} is rank-one convex, and hence continuous, on Σ; and the same for constraints on minors …

We derive a two-dimensional model for elastic plates as a Γ-limit of three-dimensional
nonlinear elasticity with the constraint of incompressibility. The resulting model describes …

The modeling of the finite elastoplastic behaviour of single crystals with one active slip
system leads to a nonconvex variational problem, whose minimization produces fine …

The macroscopic material response of a variational model in geometrically nonlinear elasto-
plasticity with two active slip systems, rigid elasticity, and hardening is determined. In …

The paper describes how to take into consideration the presence of transmissible loads in a
topology optimization method based on optimality criteria. The optimization problem has …

We consider a geometrically nonlinear model for crystal plasticity in two dimensions, with
two active slip systems and rigid elasticity. We prove that the rank-1 convex envelope of the …

Models of smectic-C liquid-crystal elastomers predict that they can display soft elasticity, in
which the shape of the elastomer changes at no energy cost. The amplitude of the soft mode …

Relaxation theorems for multiple integrals on, where, are proved under general conditions
on the integrand which is Borel measurable and not necessarily finite. We involve a …

Liquid crystal elastomers exhibit very rich elastic behaviour because they couple elastic
fields and mobile liquid crystal order. One striking phenomenon is the formation of textured …
