Elastic‐Wave Propagation in Chiral Metamaterials: A Couple‐Stress Theory Perspective

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
The intrinsic chirality of chiral metamaterials renders an effective medium based on the classical continuum theory ineffective for predicting their acoustic activity. This limitation is addressed in the present study by employing augmented asymptotic homogenization to derive a couple‐stress‐based effective medium, enabling accurate predictions in the ...

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,

Corotational Hinge‐based Thin Plates/Shells

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract We present six thin plate/shell models, derived from three distinct types of curvature operators formulated within the corotational frame, for simulating both rest‐flat and rest‐curved triangular meshes. Each curvature operator derives a curvature expression corresponding to both a plate model and a shell model.

Localized Deformation Analysis of a 3D Micropolar Modified Cam‐Clay Model

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 5, Page 1544-1562, 10 April 2025.
ABSTRACT In classical continuum constitutive models, the loss of ellipticity of the governing rate equilibrium equations entails localizing deformations and mesh sensitivity in finite element simulations. Extensions of such models rooted in the micromorphic continuum aim at remedying mesh sensitivity by introducing length scales into the constitutive ...

Micropolar Elastoplasticity Using a Fast Fourier Transform‐Based Solver

International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.
ABSTRACT This work presents a micromechanical spectral formulation for obtaining the full‐field and homogenized response of elastoplastic micropolar composites. A closed‐form radial‐return mapping is derived from thermodynamics‐based micropolar elastoplastic constitutive equations to determine the increment of plastic strain necessary to return the ...
