Improvement of finite element solution by full clamping functions
This paper presents a way for obtaining an improved finite element solution of boundary problems by estimation the principle of exact displacement method in finite element method. The displacement field is approximated by two type of functions: the basis functions satisfying the homogeneous differential equation and the full clamping element functions as a particular solution of the differential equation between the nodes. The full clamping functions represent the solution of the full clamping state on finite elements. An improved numerical solution of displacements, strains, stresses and internal forces, not only at nodes but over a whole finite element, is obtained without an increase of global basis because the potential energetic orthogonality exists between the basis functions and full clamping functions. This principle is generally applicable on different finite elements.
