| Summary |
Four-element model is generally used to understand dynamics character of high-polymer materials. However, it is difficult for this model to reproduce the Creep experiment result of ETFE film excellently. The cause is thought to be a lot of Retardation-timeτin the actual ETFE film. In this research, to understand the Creep characteristic of ETFE film, an examination using "Distribution function of Retardation-time" is conducted besides the examination by Four-element model. At the same time, the validity of the examination method by "Distribution function of Retardation-time" is confirmed.
