通过建立一类新的参考面有限单元 ,得到适用于分析层合板壳脱层屈曲问题的有限元方法·　指出了利用Mindlin假设意义下的变形协调条件 ,可以将大多数胜任层合板壳分析的一般板壳单元改造为相应的参考面单元·　这一方法确保了位移场的合理性和协调条件的满足·　为验证参考面单元的有效性 ,还对壳体脱层屈曲的几个算例作了数值分析 The finite element method suitable for analyzing the delamination buckling problem of laminated shells is obtained by establishing a new class of reference plane finite elements. It is pointed out that the deformation coordination conditions in the sense of Mindlin can be used to generalize the analysis of most qualified layered shells The conversion of the shell elements to the corresponding reference plane elements ensures that the displacement field is justified and the coordination conditions are satisfied. Several examples of delamination buckling of shells have also been made to verify the validity of reference plane elements Numerical Analysis
