A variational principle for hardening elastoplasticity
Ulisse Stefanelli
We present a variational principle governing the quasistatic evolution of a linearized elastoplastic material. In case of linear hardening, the novel characterization allows to rec…
A rate-independent model for the isothermal quasi-static evolution of shape-memory materials
Ferdinando Auricchio, Alexander Mielke, Ulisse Stefanelli
This note addresses a three-dimensional model for isothermal stress-induced transformation in shape-memory polycrystalline materials. We treat the problem within the framework of t…
Attractors for gradient flows of non convex functionals and applications
Riccarda Rossi, Antonio Segatti, Ulisse Stefanelli
This paper addresses the long-time behavior of gradient flows of non convex functionals in Hilbert spaces. Exploiting the notion of generalized semiflows by J. M. Ball, we provide…
A counterexample to regularity for parabolic fully nonlinear equations
Luis A. Caffarelli, Ulisse Stefanelli
We address the self-similar solvability of a singular parabolic problem and show that solutions to parabolic fully nonlinear equations are not expected to be .
