This paper considers the fluid–structure interaction problem of two coaxial cylinders separated by a thin layer of fluid. The flexible inner cylinder is imposed a small amplitude harmonic displacement corresponding to a dry vibration mode of an Eul

The phenomena of added (virtual) mass of the submerged structure exposed to vibration are evaluated experimentally using delta residual force vector. The proposed approach is based on the experimentally identified modal parameters i.e. natural freque

A theory of free linear vibrations of arbitrarily sagged inclined cables in a viscous fluid is presented in the framework of the heavy fluid loading concept. The static equilibrium shape of the cable is found by using the model of inextensible catena
