Abstract
This present research concerns the large deflection of smart functionally graded porous magneto-electro-elastic (FGP-MEE) composite shell structures. The accurate modeling method, based on the high-order shear deformation hypothesis, addresses scenarios involving multiple physics. The novelty of the current research lies in the introduction of a novel numerical approach that efficiently handles the non-linear behavior of MEE shells subjected to complex multi-physics loading conditions and considering FGM composite with porosities. New numerical results, physical insights and finding have been provided in the present manuscript taking into account influences of several physical factors, such as mechanical loads, external electric voltages, magnetic potentials, volume fraction index, porosity coefficient, various porosity distributions and various boundary conditions. The novel FGP-MEE model suggested in this study is highly useful for the accurate development and design of FG-MEE structures.
