DYNAMIC INCOMPATIBLE PLATE BENDING FINITE ELEMENT ANALYSIS BASED ON CORRECTED πHW FUNCTION
【摘要】 本文讨论了基于修正πHW变分的杂交应变板弯曲非协调动态有限元的分析列式,建立了四节点单元,进行了特征分析。算例表明,该单元是简单、有效的。
【Abstract】 おhis paper discusses a hybrid strain dynamic in compatible plate bending finite element technique based on the Hu-Washizu fuction corrected.A 4-node dynamic incompatible plate bending hybrid strain element has been established.Results show that the element has a good numerical characteristic.
