Effects of constrained damping and multi-segments on the hydrodynamic response of floating structures under wave action are clarified by an improved viscoelasticity-hydrodynamic coupled model, in which shear deformation of viscoelastic core constrained by surfaces bending in the floating sandwich multi-segments is modeled and coupled of the material viscoelasticity, structural dynamic, and potential flow theory. Then, higher-order hysteresis-hydrodynamic equations with articulated-separated continuity conditions, as well as velocity potential functions for plate-covered and free-water areas, are calculated using the perturbation and partition matching methods. As an illustration, a floating multi-segments structure, consisting of high-stiffness elastic-surface layers and a low-stiffness viscoelastic-core layer, is analyzed. The analytical functions of deflection, bending moment, and shear force, incorporating fluid-structure-component-material parameters, have been formulated, thereby enabling a direct assessment of the effects of constrained-damping and multi-segment configurations on hydrodynamic response to wave action, which are expected to provide new ideas for novel marine structures.
