Representation of Waves of Displacements and Micro-rotations by Systems of the Screw Vector Fields [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020 The present study concerns the coupled vector differential equations of the linear theory of micropolar elasticity formulated in terms of displacements and micro-rotations in the case of a harmonic dependence of the physical fields on time. The system is

A Top–Down Thermodynamically Motivated Perspective on Multiscale Material Modeling
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Established multiscale strategies such as QM/MM coupling, computational homogenization, quasi‐continuum approaches, and thermodynamically formulated continuum models provide powerful scale‐bridging tools, however, each of them is formulated on a different effective energetic level, and an explicit recursive energy reference structure ...

Performance of a Mixed Least‐Squares Finite Element Formulation With Application in Poroelasticity
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT A mixed least‐squares finite element method (LSFEM), previously proposed for the theory of porous media (TPM), is further investigated in this work. Finite deformation of a fully saturated, incompressible solid–fluid binary system is studied using the LSFEM.

Engineering Reports, Volume 8, Issue 10, October 2026.This study investigates Casson nanofluid flow over a porous inclined plate under magnetic field, thermal radiation, buoyancy, and chemical reaction with activation energy. A feedforward artificial neural network (ANN) is employed to solve the coupled nonlinear governing equations and predict velocity, temperature, and concentration profiles.

Turbulence Intensity Modulation by Micropolar Fluids
Fluids, 2021 Fluid microstructure nature has a direct effect on turbulence enhancement or attenuation. Certain classes of fluids, such as polymers, tend to reduce turbulence intensity, while others, like dense suspensions, present the opposite results.

Engineering Reports, Volume 8, Issue 9, September 2026.This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...

Micropolar curved rods. 2-D, high order, Timoshenko’s and Euler-Bernoulli models
Curved and Layered Structures, 2017 New models for micropolar plane curved rods have been developed. 2-D theory is developed from general 2-D equations of linear micropolar elasticity using a special curvilinear system of coordinates related to the middle line of the rod and special ...

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects
Engineering Reports, Volume 8, Issue 9, September 2026.Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.
