| 摘 要： | 板和加筋板结构的稳定性特性,是设计人员十分关注的一个问题。本文首次采用新近提出的微分求积单元法分析了各向同性加筋板的稳定性问题,建立了微分求积梁单元和板单元,并给出了详细的分析过程。通过与现有结果的对比验证了所建立的分析过程和程序的正确性。计算结果表明:微分求积单元法具有简单、收敛速度快、计算量少和精度高等优点。

| Abstract: | The new version of differential quadrature element method(DQEM) is used to analyze the stability of isotropic stiffened plates for the first time.The differential quadrature beam and the plate elements are established and the detailed procedures are given.The established methodology and the program are verified by compared the calculated results with existing data.Numerical results show that the DQEM possesses advantages of simple to be understood,good convergence rate,low time consuming,and high accuracy. |
