Title A report for creep-rupture properties of PTFE-coated membrane material Stress-displacement analysis of circular specimen for simulating a water-pressed creep test
Author Tatsuya Yoshino,Shinya Segawa,Jun Fujiwara
Summary This paper was discussed to compare between experimental and simulated results by a water-pressed creep test, using by circular specimen of membrane materials. A condition of the analysis for the simulation was shown as below;.
(1) Visco-Elast-Plastic characteristics
(2) Six-Node isoparametric curved elements
From the numerical results, the stresses distribution under creep-rupture is obtained. As for comparison with experimental and simulated results, it was the same tendency. However, at the view point of detail, there was the difference in the result. It found that performing the experiments and identifying the parameter of constitutive equations is required.
