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 …

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 …

Linearized plastic plate models as Γ-limits of 3D finite elastoplasticity

E Davoli - ESAIM: Control, Optimisation and Calculus of …, 2014 - cambridge.org
The subject of this paper is the rigorous derivation of reduced models for a thin plate by
means of Γ-convergence, in the framework of finite plasticity. Denoting by ε the thickness of …

A derivation of the time dependent von K\'arm\'an equations from atomistic models

D Buchberger, B Schmidt - arXiv preprint arXiv:2411.10233, 2024 - arxiv.org
We derive the time-dependent von K\'arm\'an plate equations from three dimensional, purely
atomistic particle models. In particular, we prove that a thin structure of interacting particles …

A Reduced Model for Plates Arising as Low-Energy -Limit in Nonlinear Magnetoelasticity

M Bresciani, M Kružík - SIAM Journal on Mathematical Analysis, 2023 - SIAM
We investigate the problem of dimension reduction for plates in nonlinear magnetoelasticity.
The model features a mixed Eulerian–Lagrangian formulation, as magnetizations are …

Dimension reduction for elastoplastic rods in the bending regime

S Neukamm, K Richter - arXiv preprint arXiv:2409.08646, 2024 - arxiv.org
We rigorously derive an effective bending model for elastoplastic rods starting from three-
dimensional finite plasticity. For the derivation we lean on a framework of evolutionary …

[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 …
