DEVELOPMENT OF NEW FINITE ELEMENT BY SOURCE METHOD

A new Finite Element by Source (FES) method is developed by the authors. FES which has a flexible geometrical shape is composed by nodes distributed on the element boundary and sources distributed out of the element boundary. The relationship between the density of sources and the boundary condition at the nodes is obtained from the combination of the fundamental solution such as Kelvin's solution for static elastic structural problems. According to this procedure, numerical analysis can be performed dealing with complex configured structures such as a ship with less mesh compared to the traditional finite element method and more accurate results can be obtained. This paper describes a fundamental theory and formulation of FES. Some examples for a static elastic structural problem using 2-D plane stress FES and 3D solid FES are also presented and compared to the theoretical solution or numerical results obtained using the traditional finite element method.
