摘要:Fibre-reinforced composite materials are increas-ingly used in marine application over the past few decadesdue to their light weight and high resistance to salt watercorrosion [1]. There materials are now being applied forcomposite pressure hulls, autonomous underwater vehicle,and even offshore oil equipment [2-7], which usually sub-ject to high pressure of seawater. For these structures, ex-ternal hydrostatic pressure-induced buckling and crushingtends to dominate structural performance.
