Strong Formulation Finite Element Method Based on Differential Quadrature: A Survey

A survey of several methods under the heading of SFEM (Strong Formulation Finite Element Method) is presented. These approaches are distinguished from classical one, termed Weak Formulation Finite Element Method (WFEM). The main advantage of the SFEM is that it uses differential quadrature method (DQM) for the discretization of the equations and the mapping technique for the coordinate transformation from the Cartesian to the computational domain. Moreover, the element connectivity is performed by using kinematic and static conditions, so that displacements and stresses are continuous across the element boundaries. Numerical investigations integrate this survey by giving details on the subject.
