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 ...

Journal of the American Ceramic Society, Volume 107, Issue 12, Page 7692-7710, December 2024.We established polydomain strain–strain phase diagrams of KxNa1 − xNbO3 thin films using the strain phase equilibrium theory. We identified two types of monoclinic polydomain structures and determined the corresponding formation conditions, the volume fractions of domain variants, and domain wall orientations by employing analytical methods and phase ...

On singular behaviour in a plane linear elastostatics problem
Mathematics and Mechanics of SolidsA vector field similar to those separately introduced by Artstein and Dafermos is constructed from the tangent to a monotone increasing one-parameter family of non-concentric circles that touch at the common point of intersection taken as the origin. The circles define and space-fill a lens-shaped region
