โœฆ Synopsis

The author has proposed a differential quadrature element method (DQEM) for numerically solving continuum mechanics problems. This method employs the differential quadrature (DQ) technique to discretize the element-based governing differential or partial differential equations, the transition conditions on inter-element boundaries and the boundary conditions on domain boundaries. A global algebraic equation system can be obtained by assembling all of the discretized equations. A rigorous solution can be obtained by solving the global algebraic equation system. In this paper, the developed two-dimensional DQEM frame model is presented. Mathematical formulations are carried out. The procedures of numerical algorithm are summarized. By using this DQEM model, accurate results of two-dimensional frame problems can be efficiently obtained. Numerical results demonstrate this DQEM model.

A new numerical approach for solving warping torsion problems is proposed. The approach uses the differential quadrature element method (DQEM) to discretize the differential equations defined on each element. The resulting overall discrete equations can be solved using the solvers of the linear alge

The purpose of this paper is to point out that in most practical situations, the Neumann kernel of two-dimensional potential theory is an analytic function of its arguments. Consequently, standard quadrature methods may normally be used for all element integrals in boundary element collocation metho
