Finite Plasticity in . Part II: Quasi-Static Evolution and Linearization

D Grandi, U Stefanelli - SIAM Journal on Mathematical Analysis, 2017 - SIAM
We address a finite-plasticity model based on the symmetric tensor P^⊤\!P instead of the
classical plastic strain P. Such a structure arises by assuming that the material behavior is …

Effective quasistatic evolution models for perfectly plastic plates with periodic microstructure

M Bužančić, E Davoli, I Velčić - Calculus of variations and partial …, 2024 - Springer
An effective model is identified for thin perfectly plastic plates whose microstructure consists
of the periodic assembling of two elastoplastic phases, as the periodicity parameter …

Quasistatic evolution models for thin plates arising as low energy Γ-limits of finite plasticity

E Davoli - Mathematical Models and Methods in Applied …, 2014 - World Scientific
In this paper we deduce by Γ-convergence some partially and fully linearized quasistatic
evolution models for thin plates, in the framework of finite plasticity. Denoting by ε the …

Effective quasistatic evolution models for perfectly plastic plates with periodic microstructure: The limiting regimes

M Bužančić, E Davoli, I Velčić - Advances in Calculus of Variations, 2024 - degruyter.com
We identify effective models for thin, linearly elastic and perfectly plastic plates exhibiting a
microstructure resulting from the periodic alternation of two elastoplastic phases. We study …

[PDF][PDF] Quasistatic evolution of magnetoelastic plates via dimension reduction

M Kruzık, U Stefanelli, C Zanini - DYNAMICAL SYSTEMS, 2015 - mat.univie.ac.at
A rate-independent model for the quasistatic evolution of a magnetoelastic plate is
advanced and analyzed. Starting from the three-dimensional setting, we present an …

Finite plasticity in

D Grandi, U Stefanelli - arXiv preprint arXiv:1509.08681, 2015 - arxiv.org
We discuss a finite-plasticity model based on the symmetric tensor $ P^ TP $ instead of the
classical plastic strain $ P $. Such a model structure arises from assuming that the material …

Linearization for finite plasticity under dislocation-density tensor regularization

R Scala, U Stefanelli - Continuum Mechanics and Thermodynamics, 2021 - Springer
Finite-plasticity theories often feature nonlocal energetic contributions in the plastic
variables. By introducing a length-scale for plastic effects in the picture, these nonlocal terms …

EXISTENCE AND LINEARIZATION FOR THE SOUZA-AURICCHIO MODEL AT FINITE STRAINS.

D Grandi, U Stefanelli - Discrete & Continuous Dynamical …, 2017 - search.ebscohost.com
We address the analysis of the Souza-Auricchio model for shape-memory alloys in the finite-
strain setting. The model is formulated in variational terms and the existence of quasistatic …
