Structures including dynamic movements such as storage and deployment are attracting attention in fields such as architecture and space. Buckling is generally known as cause of crush or an unstable phenomenon that makes it difficult to predict the shape after buckling, but the out-of-plane buckling such as slack generated in a thin film relieves stress concentration at the time of deployment and enable smoothly deployment. It also has advantages such as making it possible to construct a bi-stable structure. In this research, the authors apply a mathematical model to detect buckling, quantify the instability, visualization, response analysis after buckling, for structures with large deformation from moment to moment like storage and deployment. The authors developed the analysis code and applied some models of simple truss arch and a model of deployment of a flexible membrane. The detection, the quantification, and the visualization of the buckling was confirmed by the analyses.
