Nonlinear active control of thermally induced pyro-coupled vibrations in porous-agglomerated CNT core sandwich plate with magneto-piezo-elastic facings

Abstract In this article, the damped nonlinear transient response of a smart sandwich plate (SSP) comprising agglomerated CNT-reinforced porous nanocomposite core with multifunctional magneto-piezo-elastic (MPE) facesheets, subjected to thermal environment, is numerically investigated. The synergistic influence agglomeration, porosity and pyro-coupling on vibration control studied for first time under finite element framework. attenuation vibrations caused by active constrained layer damping (ACLD) treatment. kinematics based layer-wise shear deformation theory von-Karman’s nonlinearity. viscoelastic properties ACLD patch CNT agglomeration are mathematically modelled using Golla–Hughes–McTavish Eshelby–Mori–Tanaka methods, respectively. A comprehensive examination inter-related effects different states, distributions loading profiles has been performed. new insights controlling pyro-coupled induced plates supplying voltage directly MPE facesheets without treatment have discussed thoroughly. numerical analysis confirms significant associated SSP.
