استحکام کمانشی ورقها در ساختمان کف کشتی

To investigate buckling/ultimate strength of ship bottom plates, a series of elastoplastic large deflection analyses is performed applying finite element method. To achieve this purpose, symmetrical conditions are imposed on the plate boundaries. Also a series of elastic large deflection analyses is done in order to assess buckling behaviour and strength of continuous plates under combined lateral pressure and inplane compression.
