In this paper, the nonlinear vibration of functionally graded (FGM) cylindrical shells subjected to radial harmonic excitation is investigated. The nonlinear formulation is based on a Donnell’s nonlinear shallow-shell theory, in which the geometric nonlinearity takes the form of von Karman strains. The Lagrange equations of motion were obtained by an energy approach. In order to reduce the syst...

The effort to reduce costs and environmental impact of modern commercial aircraft requires an ever better understanding physics, including the characterisation effective damping introduced on a structure by slosh dynamics. In this paper experimental vertical sloshing dissipative behaviour rectangular tank, representative scaled wing is addressed. Specifically, controlled electrodynamic shaker e...

In the present work damping effect of sloshing flows in tanks subjected to vertical harmonic oscillations is modelled through Smoothed Particle Hydrodynamics (SPH) numerical method. The prediction energy dissipation these problems interest, among others, aeronautic field appropriately address sloshing-induced loads on aircraft wings. To this purpose, an enhanced SPH scheme applied and extensive...
