反复加载下PVC建筑膜材的应力松弛行为
Stress Relaxation Behavior of PVC Architectural Membrane under Repeated Loading
摘要
Abstract
To further investigate the stress relaxation property of membrane materials, the repeated stress relaxation property of PVC membrane was tested in this study, and the effects of initial relaxation stress, relaxation number and single relaxation time on the residual stress, repeated stress relaxation ratio and repeated stress relaxation rate were also discussed. The analytical results showed that residual stress increased with relaxation number and initial relaxation stress, and decreased with relaxation time. The repeated stress relaxation ratio increased with initial relaxation stress and single relaxation time, and decreased with relaxation number. The repeated stress relaxation rate increased with single relaxation time and relaxation number, and reduced with initial relaxation stress.关键词
