Bending, buckling, and forced vibration analyses of nonlocal nanocomposite microplate using TSDT considering MEE properties dependent to various volume fractions of CoFe۲O۴-BaTiO۳

چکیده مقاله

In this article, the bending, buckling, free and forced vibration behaviors of nonlocal nanocomposite microplate using third order shear deformation theory (TSDT) are presented. The magneto-electro-elastic (MEE) properties are dependent to various volume fractions of CoFe2O4-BaTiO3. According to Maxwell's equations and Hamilton's principle, the governing differential equations are derived. These equations discretized by using Navier’s method for a MEE nanocomposite Reddy plate. The numerical results show the influences of elastic foundation parameters; aspect ratio (l/b), length to thickness ratio (l/h), electric and magnetic fields and various volume fraction of CoFe2O4-BaTiO3 on deflection, critical buckling load, and natural frequency are investigated. Natural frequency and critical buckling load increases with increasing volume fraction of CoFe2O4-BaTiO3, also the value of amplitude vibration decreases with increasing of volume fraction. This model can be used for various nanocomposite structures. Also, a series of new experiments are recommended for future work.
