犬挠度层合板的拟协调罚单元
A QUASI-CONFORMING AND PENALTY ELEMENT OF LARGE DEFLECTION LAMINATED COMPOSITE PLATES
-
摘要: 本文将考虑耦合和剪切效应的三角形拟协调罚单元推广到对层合板的大挠度分析。数值计算证明:该单元具有良好的收敛性和足够的精度.文中用大量图表显示了边界条件,纤维铺设角,铺层数和材料弹性模量出等因素对层合板大挠度解的影响。Abstract: A fifteen-variable quasi-conforming triangle clement technique including transverse shear effect for penalty-finite element method is used to the analysis for large deflection of laminated composite plates.The calculated results reveal,that this clement has good convergence and preesion.A number of figures show the effects of boundary conditipns,fiber lay angle,the number of layers,and the clastic modull of the matorlals.
