On the wave propagation of the multi-scale hybrid nanocomposite doubly curved viscoelastic panel

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, governing equations structure derived solved with aid an analytical method. Afterward, a parametric study out investigate effects foundation, carbon nanotubes’ (CNTs’) weight fraction, various patterns, radius total thickness ratio, fibers angel on phase velocity medium. results show that, by considering viscous parameter, relation between wavenumber changes from exponential increase logarithmic boost. A useful suggestion research that fiber damping parameter hardly dependent wavenumber. presented outputs can be used ultrasonic inspection techniques structural health monitoring.
