| Title | Viscous characteristics of ETFE Film sheet - Non-linear visco-elastic constitutive equations that consider the change in temperature and biaxial creep tests - |
| Author | Tatsuya Yoshino, Shiro Kato |
| Summary |
In this research, the target is to clarify the behaviour of the membrane structure of the ETFE film using the FEM analysis. ETFE film shows the behavior of both of elasto-plastic characteristics and visco-elastic characteristics. The authors have carried out researches focusing on these characteristics. This paper will focus on visco-elastic characteristics when temperature changes during biaxial tension creep tests. First, biaxial creep tests accompanied with temperature change are performed. During the tests, thermal strain and creep strain are recorded against different types of tension ratios. Second, the incremental constitutive equations - proposed in previous paper - are used to carryout simulation of biaxial creep tests accompanied with temperature change. Then, validity of the proposed incremental constitutive equations is to be proofed |
