Nonlinear deflection of carbon nanotube reinforced multiphase magneto‐electro‐elastic plates in thermal environment considering pyrocoupling effects

Abstract

The primary focus of this article is on assessing the influence of pyroeffects on the nonlinear coupled deflections of carbon nanotube (CNT) reinforced multiphase magneto‐electro‐elastic (MMEE) plates. A finite element procedure incorporating Reddy's higher order shear deformation theory (HSDT) and von Karman's nonlinear strain‐displacement relation is employed to obtain governing equations. The solutions are obtained via direct iterative method. The different volume fractions of piezoelectric and piezomagnetic phases have been considered. Also, the various forms of CNT distributions that significantly affect the coupling characteristics of the CNT‐MMEE plate have been considered. The numerical examples reveal that the pyroelectric and pyromagnetic effects play a vital role in predicting accurate structural responses. Further, this article also attempts to evaluate the effect of electro‐magnetic circuits and electro‐magnetic loads associated with the pyrocoupling, which is first of its kind. It is found from this study that the non‐dimensional deflections of CNT‐MMEE plate vary predominantly with the pyroeffects and electro‐magnetic circuits.

Effect of carbon nanotube-reinforced magneto-electro-elastic facings on the pyrocoupled nonlinear deflection of viscoelastic sandwich skew plates in thermal environment

“…Furthermore, the face sheets are made of FG-CNTMEE materials, whose effective properties can be described through the rule of mixture. The constitutive equations of FG-CNTMEE are expressed as follows 54 : in which \where the volume fraction of various CNTs’ distributions in FG-CNTMEE can be mathematically expressed using where V CNT * = w CNT / false[ w CNT + false( ρ normalCNT / ρ m false) − false( ρ normalCNT / ρ m false) w CNT false] and w CNT represents the mass fraction of CNT.…”

“…Very recently, the nonlinear free vibration 52 and deflection analysis 53 of CNT-reinforced MEE (CNTMEE) shells were studied by Mahesh and Harursampath 53 and Vinyas and Harursampath. 52 Meanwhile, the effect of pyrocoupling on the nonlinear deflection of multiphase MEE plates was probed by Mahesh 54 through the FE approach.…”

Simulation-based assessment of coupled frequency response of magneto-electro-elastic auxetic multifunctional structures subjected to various electromagnetic circuits

“…Several studies focused on assessing the thermal response of MEE plates, beams, and shells considering pyroelectric and pyromagnetic effects. [33][34][35][36][37] The pyroeffects were seen to be suppressed by the application of electromagnetic loads. Discrepancies in the existing MEE media in the form of cracks or the addition of fluid interfaces can affect the vibrational performance of MEE structures.…”

P-type α-Fe2O3 hexagonal nanosheets: Synthesis and aniline-sensing performance

“…And they have been widely applied to electrodes, gas sensing, catalysis, magento-electro-elastic materials, and other fields. [21][22][23][24][25][26][27][28][29][30] In this work, we have designed a p-type a-Fe 2 O 3 hexagonal nanosheets (NSs) sensor for aniline detection and adopted a low-cost solvothermal and annealing methods to obtain the sample. The synthesized sample exhibits unusual p-type conductivity rather than typical n-type conductivity and the reason of unusual performance is investigated and discussed specifically.…”
