On an Optimal AFEM for Elastoplasticity
Computational Methods in Applied MathematicsAbstract In this paper, optimal convergence for an adaptive finite element algorithm for elastoplasticity is considered. To this end, the proposed adaptive algorithm is established within the abstract framework of the axioms of adaptivity [C. Carstensen, M. Feischl, M. Page and D. Praetorius, Axioms of adaptivity, Comput. Math. Appl.

Dimension reduction for elastoplastic rods and homogenization of elastoplastic lattices
, 2021 We derive effective equations for periodic lattices of linearly elastoplastic rods in the limit of both infinitesimal periodicity and infinitesimal relative width of the rods. For this derivation we use the method of evolutionary Γ-convergence for quadratic rate-independent systems.

Research on the Neutral Layer Deflection Phenomenon in Three-Dimensional Stretch Bending of Profiles
MetalsThis paper aims to study the deflection phenomenon of the neutral layer in the cross-section of profiles during the 3D stretch-bending process. By establishing the displacement field for both the stretching and bending processes of a profile with ...

Pipelines and laterally loaded piles in an elastoplastic medium
, 1993 The uplift behavior of a shallow pipeline embedded in an elastoplastic medium is examined. An analytical solution for a beam on elastoplastic foundation is developed and a characteristic nondimensional load‐displacement and stress‐displacement ...

A mathematical model of network elastoplasticity
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 We introduce a mathematical model, based on networks, for the elasticity and plasticity of materials. We define the tension tensor for a periodic graph in a Euclidean space, and we show that the tension tensor expresses elasticity under deformation. Plasticity is induced by local moves on a graph. The graph is described in terms of the weights of edges,

Engineering and Applied Science Research, 2021 In this work we exanimate, in elastoplastic case, the crack growth in P265GH material, we use eXtended finite element method (XFEM) in the Cast3m code. Crack growth in the 3D CT pipe sampleis modeled using stress intensity factor and J integral.

Advanced Science, EarlyView.This work presents an origami metamaterial that integrates a low‐melting‐point alloy skeleton into an elastomeric shell. It dissipates energy through the metal's plastic deformation and recovers through the solid–liquid phase transition of the alloy together with the hyperelasticity of the shell.
