this study investigates natural frequency analysis of an fg composite rectangular plate partially contacting with a bounded fluid. the material properties are assumed to be varying continuously through the thickness direction according to a simple power law distribution in terms of volume fraction of material constituents. wet dynamic transverse displacements of the plate are approximated by a ...

We consider the problem of active reduction of the structural vibrations induced by the sloshing of large masses of fuel inside a partly full tank. The proposed study focuses on an experimental device mimicking an aircraft wing made of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid. After deri...

A spectral/hp element code, incorporating a velocity-pressure formulation, is used to simulate free surface flows. Non-linear pressure and velocity boundary conditions are applied on the moving free surface, the tracking of which is facilitated by the implementation of an Arbitrary Lagrangian Eulerian (ALE) formulation. The derived algorithm is validated by comparing the numerical results evalu...
