复合材料叠层板弯曲有限元分析中的一种应力杂交元

A HYBRID-STRESS ELEMENT FOR BENDING ANALYSIS OF COMPOSITE LAMINATED PLATES

本文提出了一种适合各种厚度复合材料叠层板弯曲分析的应力杂交元模式。当板厚度变薄时此模型不会发生Mindlin板的闭锁现象。与Spilker文中所提出的V2元素比较,在保持相同精度的情形下,可以大量节约计算机时及内存。

The paper proposes a hybird stress element for bending anal ysis of composite laminated plates with various thickness.The element does not display locking phenomenon of Mindlin plates when it becomes thin.Compared with the V2 element by Spilker, the present element can largely save CPU time and in-core storage while maintaining the same accuracy.
