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. © 2020 John Wiley & Sons, Ltd.
