基于“单独单元试验”的层合板有限元
A LAMINATED PLATE ELEMENT BASED ON THE “INDIVIDUAL ELEMENT TEST”
-
摘要: 本文利用Bergan的“单独单元试验”(简写为IET)和“自由公式”,提供了一个具有拉-弯耦合效应的复合材料层合板单元,对典型问题的数值计算表明其性能良好。Abstract: For the purpose of applying the Bergan's "individual clement test" and "frce formulation",this paper suggests a laminated plate element including bend-exctensional coupling.The numerical results of some sample problem show that this clement is satisfying.
