| Summary |
Young's Modulus and yield stress of macromolecular materials are generally dependent on strain velocity. The effects of these characteristics on the tensile properties of ETFE films are clarified through the single and cyclic tensile experiments, and the differences of yield stress are verified against several strain velocity conditions. The effects of those properties on structural characteristics of ETFE film structures are examined by the comparison of the experiment with FEM analysis of pressurized ETFE file fixed on round boundary.
