Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Characterization of the Induced Magnetic Field on Third-Grade Micropolar Fluid Flow Across an Exponentially Stretched Sheet

Frontiers in Physics, 2022
The current research article discusses the two-dimensional, laminar, steady, and incompressible third-grade viscoelastic micropolar fluid flow along with thermal radiation caused by an exponentially stretched sheet.

MHD THREE-DIMENSIONAL STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]

, 2011
The steady three-dimensional stagnation-point flow of an electrically conducting micropolar fluid in the absence and in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined. In particular,

Equivalent variational approaches to biaxial liquid crystal dynamics

, 2015
Within the framework of liquid crystal flows, the Qian & Sheng (QS) model for Q-tensor dynamics is compared to the Volovik & Kats (VK) theory of biaxial nematics by using Hamilton's variational principle.

Dual Solutions of Non‐Newtonian Micropolar Nanofluid Flow and Heat Transfer Over a Stretching/Shrinking Surface With Chemical Reaction and Lorentz Forces

Engineering Reports, Volume 8, Issue 4, April 2026.
This plot represents the flow configuration of the two‐phase nanofluid model. The dynamics of boundary layer micropolar nanofluid flow, heat and mass transfer characteristics past a vertical exponentional stretching/shrinking sheet in the presence of chemical reaction and thermal raditaion effects are investigated. In addition, the Lorentz and buoyancy

On micropolar fluid theory [PDF]

, 2019
New fundamental solutions for an incompressible micropolar fluid have been obtained in an explicit form by considering a three-dimensional Oseen flow due to a point force and a point couple. Fundamental solutions that do not exist in classical flows have also emerged in this study owning to the existence of the microrotation velocity field in a ...

Exact controllability of Galerkin’s approximations of micropolar fluids [PDF]

Proceedings of the American Mathematical Society, 2009
We consider the nonlinear model describing micropolar fluid in a bounded smooth region of R N ( N = 2 , 3 ) \mathbb {R}^{N} (N=2,3) with distributed controls supported in small subset of this domain.
