Closed Form Relations and Higher‐Order Approximations of First and Second Derivatives of the Tangent Operator on SE(3)

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 4, April 2026.
ABSTRACT The Lie group SE3$SE\left(3\right)$ of isometric orientation‐preserving transformation is used for modeling multibody systems, robots, and Cosserat continua. The use of these models in numerical simulation and optimization schemes necessitates the exponential map, its right‐trivialized differential (often referred to as the tangent operator ...

Magneto‐X Effects in Magnetic Soft Materials and Their Applications

Advanced Science, Volume 13, Issue 18, 27 March 2026.
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,

On Finite Element Computations of Contact Problems in Micropolar Elasticity

Advances in Materials Science and Engineering, 2016
Within the linear micropolar elasticity we discuss the development of new finite element and its implementation in commercial software. Here we implement the developed 8-node hybrid isoparametric element into ABAQUS and perform solutions of contact ...

Numerical and Analytical Study of Elastic Parameters in Linearized Micropolar Elasticity

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT The effect of elastic parameters in the linearized theory of micropolar elasticity on observable deformation is analyzed analytically and numerically. Specifically, a shear deformation boundary value problem is studied to explore the physical implications of a micropolar formulation. Our new analytical solution for the two‐dimensional shearing

Cubic Lattice Rib Shape: Tuning of Poisson's Ratio and Cosserat Characteristic Length

physica status solidi (b), Volume 263, Issue 3, March 2026.
Cubic rib lattices are studied in the context of effects of rib cross‐section shape on Poisson's ratio and on Cosserat characteristic length. It is possible to control Poisson's ratio over a wide range via appropriate rib cross‐section shape. Both Cosserat characteristic lengths can be made much larger than the cell size for torsion dominated rib ...

Electromagnetic interaction on micropolar fluids.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1989
Basic equations for micropolar fluids in an electromagnetic field have not been established yet. In this paper, relativistic electromagnetic interactions on micropolar fluids are investigated by electromagnetic exergy. We obtained the results that electromagnetic momentum for micropolar fluid is well defined as g=D×B and an isotropic part of Maxwellian

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...
