The hydrostatic stiffness of flexible floating structures for linear hydroelasticity

摘要: The formulation of the hydrostatic stiffness for linear rigid body hydrodynamics is well known. An explicit an analogous in hydroelasticity, which applicable to both and flexible displacement, not as well-known. Three such formulations have been proposed previously literature, none quite correct; all produce unsymmetric matrix. complete floating structures at rest calm water derived based on a consistent linearization external pressure internal structural stresses. symmetry present structure proven analytically, unsymmetry individual finite elements discussed. will be most interest those who wish extend potential theory hydrodynamic codes analysis deformable bodies. Several issues that are significant practical implementation discussed several examples presented.
