The effect of the foam structure and distribution on the thermomechanical vibration behavior of sandwich nanoplates with magneto-electro-elastic face layers

Abstract

This study examined the thermal vibration of a foam core nanoplate composed of ceramic silicon nitride (Si3N4) and metal biomaterial (Ti-6Al-4V) in the core layer, and cobalt-ferrite (CoFe2O4) and barium-titanate (BaTiO3) in the face layers. The constitutive equation is influenced by various factors, including nonlocal elasticity, thermal expansion, strain gradient elasticity, magnetostrictive, and electroelastic properties, as well as sinusoidal higher-order shear deformation theory (SHSDT) with stretching effect. The study found that the thermomechanical vibration behavior of nanoplates was influenced by the ratio of open cell foam to solid, nonlocal factors, thermal load, electrical and magnetic potentials, and different foam distribution.
