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.

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation
Computer Graphics Forum, EarlyView.A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

Isogeometric analysis of linear isotropic and kinematic hardening elastoplasticity
Vietnam Journal of Mechanics, 2017 Material nonlinearity is of great importance in many engineering problems. In this paper, we exploit NURBS-based isogeometric approach in solving materially nonlinear problems, i.e. elastoplastic problems.

Accuracy of next‐generation wireless skin temperature sensors during exercise–heat stress
Experimental Physiology, EarlyView.Abstract Skin temperature is fundamental in characterising human thermoregulatory responses. Wired probes, although accurate, restrict movement and are impractical outside laboratory settings. The iButton (DS1922L; Maxim Integrated, USA) is a widely used wireless alternative but does not meet the precision recommended by ISO 9886 and permits only ...

Closed system of coupling effects in generalized thermo-elastoplasticity
International Journal of Applied Mechanics and Engineering, 2016 In this paper, the field equations of the generalized coupled thermoplasticity theory are derived using the postulates of classical thermodynamics of irreversible processses. Using the Legendre transformations two new thermodynamics potentials P and S

GAMM-Mitteilungen, Volume 49, Issue 3, September 2026.Abstract This article investigates the modeling of metallic isotropic porous materials by evaluating and comparing macroscopic and microstructure‐resolved simulation approaches. At the macroscopic level, different variants of the Deshpande‐Fleck (DF) model are implemented to describe the elastoplastic behavior of metallic porous materials.

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4339-4359, 10 August 2026.ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.
