Dynamic structure-fluid interaction response of a composite cylindrical shell submerged in water

This paper analyzes the dynamic structure-fluid interaction response of a s ubmerged composite cylindrical shell. Dynamic equations based on the first- order shear deformation theory include the initial stresses and structure-f luid interaction forces due to fluid. The field equation is solved by expan ding the velocity potential into series similar to transverse deflection of the cylindrical shell and the structure-fluid interaction force is obtaine d. The dynamic response is investigated by means of series expansion method . The effects of structure-fluid interaction on dynamic response are discus sed.
