The restoring stiffness, that couples displacements and deformations, plays very important role in hydroelastic analysis of marine structures. The problem of its formulation is quite complex and is still discussed in the relevant literature. In the paper, the recent formulations of restoring stiffness are correlated and analyzed. Due to some equivalent(More)
e-mail: neven.hadzic@fsb.hr The signifi cant growth of renewable energy production in the past decades is present mainly due to the global depletion of fossil fuel reserves. One of interesting and well developed renewable energy technologies are wind turbines which are mainly built onshore. Due to more favorable wind characteristics at sea, off shore wind(More)

Relatively simple analytical procedures for the estimation of natural frequencies of free thin rectangular plates, based on the Rayleigh quotient and the Rayleigh-Ritz method, are presented. First, natural modes are assumed in the usual form as products of beam natural modes in the longitudinal and transverse directions, satisfying the grillage boundary(More)

The aim of the paper is to review practical methods for structure born noise propagation assessment in complex ship structures. Three methods are reviewed: the Finite Element Method (FEM), the Statistical Energy Analysis (SEA) and the Energy Finite Element Method (EFEM). A brief theoretical background of the methods is provided together with inherent(More)
