在固体力学问题的有限元计算中,常采用选择约化积分法(SRI)来消除闭锁现象。通常,SRI相当于混合方法的应用。当应用多重网格方法时,作为混合方法的公式是迄今为止优越的上级。这一点可以通过对梁的分析来证明。
SummaryIn the finite element calculations of problems in solid mechanics the method of selected reduced integration (SRI) is frequently used to eliminate locking phenomena. Often SRI is equivalent to the application of a mixed method. When multigrid methods are applied, the formulation as a mixed method is by far superior. This is shown by an analysis of the Timoshenko beam.
