A hydroelastic model is developed to study the interaction of linear long gravity waves with a very large floating flexible plate resting on viscoelastic foundation, which based Kelvin–Voigt model. Flexural wave blocking occurs for specific values compressive force in absence viscous damping. During blocking, group velocity vanishes, and mode swapping occurs. Within buckling limit presence force, three distinct propagating modes occur Moreover, reveals that irrespective damping constant,...

We present a stable meshless scheme for numerical solution of 2D Helmholtz equation using radial basis-finite difference (RBF-FD) method. The interpolants over 'user defined' node arrangement are computed through hybrid Gaussian-cubic kernel. Such kernel reduces the ill-conditioning problem in discretization, therefore, making it applicable to problems with relatively larger degrees freedom. Numerical tests demonstrate that presented RBF-FD has significant improvements standard mesh-based...
