摘要
概述了膜结构的找形概念和物理模型方法。论述了常用的力密度法、动力松弛法、非线性有限元法等3种找形方法的基本原理及各自的特点。介绍了这3种找形理论的新发展。
In the paper, the membrane structures shape -seeking concept and physically modeling method are briefly summarized. The basic fundamentals and the respective characteristics of the commonly - used three shape - seeking methods of force density, dynamic relaxation and nonlinear finite element are discussed. And the development of the three shape - methods is also explained. seeking
