✦ Synopsis

Based on Hellinger}Reissner functional and with the inclusion both of displacements and stresses, a hybrid stress formulation of dynamic "nite element method is derived in this paper. In this formulation, the displacements are separated into zeroth displacement modes and high-order incompatible dynamic displacement modes which are related to the dynamic characteristics. The rationality, feasibility and e!ectiveness of the present method are also numerically justi"ed.

A new method of formulating isoparametric finite element is developed, and the element strains are proposed to be resolved into two parts, constant part and higher-order one. The new method indicates two important properties of isoparametric finite element, and the equivalent relationship between hy

In this paper we are concerned with a weighted least-squares finite element method for approximating the solution of boundary value problems for 2-D viscous incompressible flows. We consider the generalized Stokes equations with velocity boundary conditions. Introducing the auxiliary variables (stre
