In this paper, wave propagation analysis of multi-hybrid nanocomposite (MHC) reinforced doubly curved panel embedded in the viscoelastic foundation is carried out. Higher-order shear deformable theory (HSDT) utilized to express displacement kinematics. The rule mixture and modified Halpin–Tsai model are engaged provide effective material constant MHC panel. By employing Hamilton’s principle, go...
