3D NUMERICAL SIMULATION OF INTERACTION OF FULLY NONLINEAR WATER WAVES WITH FINITE FLOATING ELASTIC PLATE

In this work, a meshless method is used to investigate the 3D interaction of fully nonlinear water waves with floating plate. It is assumed that the fluid is homogenous, inviscid and incompressible. Large deflection of thin elastic plates is governed by two coupled nonlinear Von-Karman differential equations. Fundamental solution of the Laplace equation is considered to be radial basis function (RBF). Moreover, the B-spline basis functions areconsidered to fit the plate and free water surfaces. Also, in order to apply the effect of edge plate conditions, the multiple knot B-spline functions are used
