Abstract

The yield set of a polycrystal is characterized by means of a variational principle in L∞L^\infty obtained via Γ-convergence of a class of power-law functionals in the setting of A\mathcal{A}-quasiconvexity. Our results apply, in particular, to the model cases of antiplane shear and plane stress plasticity.
