  • By aid of the penalty function method, the equilibrium restriction conditions were intr oduced to the isopar ametric hy brid finite element analysis, and the concrete application course of the penalty function method in three-dimension isoparametric hybrid finite element was discussed. The separated penalty parameters method and the optimal hybrid element model with penalty balance were also presented. The penalty balance method can effectively refrain the par asitical stress on the premise of no additional degrees of freedom. The numeric experiment shows that the prese ntedelement not only is effective in improving greatly the numeric calculation precision of distorted grids but also has universality.
