This study verifies wrinkle-scaling law through photogrammetric measurement for a rectangular membrane subjected to shear and tensile loads. The wrinkle-scaling law treated in this study indicates that a wrinkle amplitude ratio during a formation and a dissipation process of wrinkle are determined by the ratio of a virtual shrinkage strain to a major principal strain, which is not affected by a membrane size. A formation and a dissipation process of wrinkles on five rectangular isotropic membranes with different sizes were measured by photogrammetry, and the relationship between the wrinkle amplitude ratio and the strain ratio was discussed. The results showed that the relationship between the wrinkle amplitude ratio and the strain ratio is linear, which represents the scaling law, regardless of the membrane size, while confirming the validity of the scaling law. This paper also presents a utilization method of the wrinkle-scaling law to a practicable situation using photogrammetric measurement.
