A data-driven reduced-order surrogate model for entire elastoplastic simulations applied to representative volume elements [PDF]
Scientific Reports, 2023 This contribution discusses surrogate models that emulate the solution field(s) in the entire simulation domain. The surrogate uses the most characteristic modes of the solution field(s), in combination with neural networks to emulate the coefficients of

An approach to elastoplasticity at large deformations [PDF]
European Journal of Mechanics, A/Solids, 2013 Finite plasticity theories are still a subject of controversy and lively discussions. Among the approaches to finite elastoplasticity two became especially popular. The first, implemented in the commercial finite element codes, is based on the introduction of a hypoelastic constitutive law and the additive elastic-plastic decomposition of the ...

A mathematical model of network elastoplasticity. [PDF]
Proc Math Phys Eng Sci, 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,

Schmidt-Ishlinskii Yield Criterion and a Rotating Cylinder with a Rigid Inclusion [PDF]
Journal of Applied and Computational Mechanics, 2021 An elastoplastic rotating cylinder with a rigid inclusion and fixed ends is investigated. The analysis is based on infinitesimal strain theory, Schmidt-Ishlinskii yield criterion, and its associated flow rule and perfectly plastic material behavior. Both

State-dependent non-orthogonal elastoplastic constitutive model for sand
Yantu gongcheng xuebao, 2023 The mechanic characteristics of sand have obvious features of state dependence, which is mainly reflected by the fact that the deformation characteristics of sand in different stress and density states significantly differ. The reasonable description for
