A General-Purpose Element-Based Approach to Compute Dispersion Relations in Periodic Materials with Existing Finite Element Codes
(World Scientific Publishing Co. Pte LtdUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2019-01-01)
The numerical determination of dispersion relations in periodic materials via the finite element method is a difficult task in most standard codes. Here, we propose a novel technique which allows the computation of these ...
Taylor-petrov-galerkin method for the numerical solution of KdV equation
(Hikari Ltd., 2016-01-01)
In order to find the approximate solution of the KdV equation, we use the finite element method of Taylor-Petrov-Galerkin, in which discretization in the time variable is carried out using Taylor series expansion and for ...
