Abstract Galerkin weighted residual method (GWRM) is applied and implemented to address the axial stability bifurcation point of a functionally graded piezomagnetic structure containing flexomagneticity in thermal environment. The continuum specimen involves an exponential mass distributed heterogeneous media with constant square cross section. physical neutral plane investigated postulate mate...

We propose a novel acousto-optic (AO) devise using suspended fishbone nanobeams based on phononic and photonic potential well (PnPW PtPW). aim to reduce the traditional device size eliminate need for mirror regions in 1-D nanobeam cavity. By manipulating frequencies of slow sound (SS) light (SL) modes through geometric parameters, we can create wells phonons photons. The concentrate waves insid...

Recent developments have shown that the widely used simplified differential model of Eringen’s nonlocal elasticity in nanobeam analysis is not equivalent to corresponding and initially proposed integral models, pure two-phase model, all cases loading boundary conditions. This has resolved a paradox with solutions are line expected softening effect theory appears other cases. In addition, it rev...

The aim of this paper is to study the electro-mechanical coupling responses functionally graded (FG) piezoelectric cantilever nanobeam under concentrated load, and material properties follow an exponential distribution in thickness direction. constitutive equations are derived from electric Gibbs free energy density function. governing boundary conditions Euler–Bernoulli FG beam can be obtained...
