Buckling Response of Functionally Graded Porous Plates Due to a Quasi-3D Refined Theory

open access: yesMathematics, 2022
A quasi-3D refined theory is used to investigate the buckling response of functionally graded (FG) porous plates. The present theory takes into consideration the effect of thickness stretching. Three models of FG porous plates are presented: an isotropic

Refined Beam Theory for Geometrically Nonlinear Pre-Twisted Structures

open access: yesAerospace, 2022
This paper proposes a novel fully nonlinear refined beam element for pre-twisted structures undergoing large deformation and finite untwisting. The present model is constructed in the twisted basis to account for the effects of geometrical nonlinearity ...

Refined topological amplitudes from the Ω-background in string theory

open access: yesJournal of High Energy Physics, 2022
It was recently shown that the N $$ \mathcal{N} $$ = 2 string topological amplitudes in the heterotic weak coupling limit generate a six-dimensional Melvin space, providing a description of the Ω-background in string theory, where string propagation can ...
