An Energy Method Based on Continuum Mechanics for Accurate Determination of Stresses and Deflections of Submarine Hull and Foundation Structures under Hydrostatic Loading

摘要

Detailed mathematical theories and computational techniques are described for the development of an experimentally proven computerized energy method which is based on the continuum mechanics and aimed at the accurate determination of stresses and deflections of a typical submarine hull and foundation structures under hydrostatic loading. The procedure is extended, briefly, for dealing with dynamic loadings as well as the effects of nonlinearities resulting from large structural deflections and/or plastic flow.
