摘要
本文用有限元法分析正交异性板的弹性稳定性问题,介绍了一种十分有效的任意四边形板弯曲单元体。数值结果说明,此种单元用于正交异性极的稳定性分析能得到很好的结果。此外,对正交异性中厚板的屈曲问题,本文也做了初步的探讨。
Elastic stability problems of orthotropic plates arc discussed through the finite element approach. An effective quadrilateral bending element is presented. It is shown by the numerical results that a good solution can be obtained by applying this clement in stability analysis of orthotropic plates. In addition preliminary discussions are also made of the buckling problems of moderately thick orthotropic plates
