| Summary |
An incremental method which uses selected biaxial testing data is proposed for non-linear elastic analysis of membrane structures. This method consists of three steps in each incremental stage; obtaining approximate warp and fill strains using material law used in the previous incremental stage. building a new material law using biaxial testing data near the approximate strain path. and solving the problem using the new material law. This method is compared with the conventional material linear analysis and a method using polynomial functions of strain for stress on their accuracy based on an experiment. The experiment shows greater accuracy using the method proposed in the present paper.
