Temperature-dependent deformation of methane hydrate within phase boundary
Journal of Materials Research and TechnologyNatural gas hydrates preserve a huge amount of methane, yet are highly sensitive to temperature fluctuations, especially under conditions close to the phase equilibrium boundary.

On a recursive formulation for solving inverse form finding problems in isotropic elastoplasticity
Advanced Modeling and Simulation in Engineering Sciences, 2014 BackgroundInverse form finding methods allow conceiving the design of functional components in less time and at lower costs than with direct experiments.

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Dynamics of the Euler — Bernoully beam with distributed hysteresis properties
Вестник Самарского университета: Естественнонаучная серияIn this paper, we present a new mathematical approach to the analysis of a beam with distributed hysteresis properties. These hysteresis characteristics are described by two methods: phenomenological (Bouc — Wen model) and constructive (Prandtl ...

Smoothed finite element method for two-dimensional elasto-plasticity
Vietnam Journal of Mechanics, 2009 This communication shows how the smoothed finite element method (SFEM) very recently proposed by G. R. Liu [14] can be extended to elasto-plasticity. The SFEM results are in excellent agreement with the finite element (FEM) and analytical results.

Hybrid-Trefftz stress elements for three-dimensional elastoplasticity
Computer Assisted Methods in Engineering and Science, 2023 The stress model of the hybrid-Trefftz finite element formulation is applied to the elastoplastic analysis of solids. The stresses and the plastic multipliers in the domain of the element and the displacements on its boundary are approximated.
