薄膜体系找形设计中二次找形方法的提出及其力学原理

THE CONCEPTION AND PRINCIPLE OF SECOND SHAPE FINDING IN MEMBRANE STRUCTURE SHAPE FINDING DESIGN

    摘要
  • 摘要: 介绍了利用非线性有限元法进行薄膜体系找形分析的相关理论和相应的有限元计算公式,在此基础上提出了二次找形的概念,指出只有通过二次找形后得到的曲面才是在工程实践中能够真正实现的形状,并通过理论和工程算例证明了本方法的正确性和有效性。

     

    Abstract: In this paper, the relative theory and its corresponding finite element calculation formula about the shape finding of membrane structure is introduced. The conception of second shape finding is presented. It is pointed out that only the curved surface obtained after the second shape finding process is realizable in pactice. The validity and practicality of this second shape finding method is demonstrated.
