A recent study has explored the complex nonlinear wave dynamics and structural response of open shells made from hybrid nanocomposites. These materials, composed of multiple layers of graphene and carbon nanotubes, are subjected to aerodynamic forces and rest on an elastic foundation with friction. The research focuses on understanding how these external forces interact with the material's internal structure, generating nonlinear wave behaviors that are crucial for the design of advanced structures in aerospace engineering and other high-demand applications.

The work addresses a fundamental problem in materials mechanics: predicting the behavior of lightweight and strong structures under extreme conditions. The inclusion of graphene and carbon nanotubes imparts superior mechanical properties to these materials, but also introduces significant complexity in their analysis due to their heterogeneous nature and nanoscale interactions. The elastic foundation with friction adds another layer of realism to the model, simulating support conditions common in practical applications that directly influence wave propagation and structural stability.

To conduct this analysis, the researchers employed an approach combining higher-order shell theory with advanced numerical methods. This method accurately captures the effects of geometric and material nonlinearity, as well as the influence of the viscoelastic properties of the foundation. The results provide a detailed understanding of the vibration modes, wave amplitudes, and stress distribution in the shells, revealing how the nanocomposite configuration and the characteristics of the elastic foundation affect the overall dynamic response of the structure.
