The Computation of Stiff and Elastic Features of Structures with Time Domain Analysis

Hydroelasticity of marine structures with and without forward speed is studied directly using time dependent Boundary Integral Equation Method Neumann-Kelvin linearisation where the potential considered as impulsive velocity potential. The exciting radiation hydrodynamic parameters are predicted in transient wave Green function whilst structural analysis solved Euler-Bernoulli beam method at which modeshapes defined analytically. modal used to approximate hydroelasticbehaviour floating systems through fully coupling analyses. As it expected, found numerical experience that effects rigid body modes greater than elastic case stiff structures. results present in-house computational tool ITU-WAVE compared experimental for validation purposes show acceptable agreements.
