Structural analyses of cylindrical FRP shells subjected to hydrodynamic and wind pressures

Abstract

Stresses and displacements in the cylindrical FRP monocoque shells with various shape parameters subjected to the hydrodynamic and wind pressure distributions are analyzed by use of shell theory considering unsymmetrical deformations. Some useful formulas and design charts are presented for obtaining the maximum stresses and displacements in these cylindrical FRP shells. As a result, it was found that the significant bending and shear stresses occurred in thinner and taller cylindrical FRP shells. These stresses can cause a failure of these shells.
