研究了用于复合材料板、壳结构分析的退化的等参壳元．数值计算结果表明，该单元不仅适合厚的和中厚的复合材料板、壳结构的分析，而且在采用了“节减积分”或“选择积分”技术之后，也同样适合复合材料薄板和薄壳的计算．
The degenerate isoparametric shell elements for composite plate and shell structures were studied. The numerical calculation results show that this unit is suitable not only for the analysis of thick and medium-thickness composite plates and shell structures, but also for the composite sheet and shell after adopting “reduction of integration” or “selection integration” techniques. Calculation.
