Failure Modes of Laminated Axisymmetric Shells of Revolution Subjected to External Pressure

Abstract

The paper deals with the investigations of failure modes of laminated shells of revolution subjected to external pressure. These are analysed for two typical shell forms such as fully clamped hemispheres and torispheres made of unidirectional or woven roving glass/epoxy and carbon/epoxy. The buckling pressures of composite shells are compared with the failure pressures obtained from the various failure criteria in the stress space. The effects of fibre orientation and initial geometric imperfections are also discussed. The imperfections considered are in the form of increased-radius polar imperfections and Legendre polynomial imperfections. For CFRP perfect torispherical shells the numerical results are verified by experimental tests.
