Stability Analysis of Composite Cylindrical Shell Containing Rotating Fluid

A semi-analytical finite element method is used to analyze the stability of composite cylindrical shells interacting with a rotating fluid inside them. mathematical formulation problem deformable structure dynamics based on variational principle virtual displacements and classical shell theory. The behavior an ideal compressible described within framework potential validity obtained results supported by comparing them known solutions. Numerical experiments were performed for two- three-layer cross-ply made boron-epoxy resin different boundary conditions geometrical dimensions. It demonstrated that, examined configurations, increase in fibre angles leads significant critical rotation velocities fluid, regardless fixing edges thin-walled structure.
