| Abstract | ||
| This research is devoted to explore the nonlinear vibration characteristics of smart nanoshells under multi-phyisical magneto-electric fields. The nano-scale shell has been treated as a thin shell with prescribed curvature which is modeled by nonlocal elasticity theory. The material composition of the smart nanoshell has been considered as a two phase composite for which the effective properties depend on the percentage of each phase. The discretization of governing equations has been carried out based on differential quadrature method (DQM). It has been exhibited that nonlinear vibration properties of curved nanoshells rely on nonlocality coefficient, piezoelectric phase percentage, radius of curvature, and electrical/magnetic potential. | ||
