Wrinkling on structed circular membranes under inplane torsion -experiments with polyester films and coated fabrics-

摘要

The problem of circular stretched membranes under inplane torsion is a typical example in studying wrinkling on membrane structures. In this paper experiments of the example are carried out. A feature of the experiment is that both isotropic polyester films and orthotropic coated fabrics are treated, since membranes used in spatial architectures are usually or- thotropic. Few studies on wrinkling on orthotropic membranes can be found. Another feature of the experiment is that stresses in the wrinkled membranes are measured.
