| Abstract Scope |
This paper analyzes the multiple stable states of a corrugated shell structure, where the unit cell is the bistable tape spring. The two stable states of the tape spring are obtained through a local antisymmetric material layup. This study shows that the overall stable configuration of the tape spring can be controlled through local steering of the fiber paths within each ply of the composite. Consequently, by steering the fiber paths across each unit cell of the corrugated shell composed of multiple tape springs, multiple stable states can be obtained along with control of the global configuration. The analysis reveals that the steering of the local fiber orientation introduces an additional degree of freedom, enabling the precise control over the stable states of the shell. The primary emphasis of this study lies in the inspection of local stability to exert control over the overall shape and configuration of the shell in its equilibrium states. A comprehensive analytical and numerical analysis, using a finite element approach is conducted to understand the bistable behavior of the tape spring shell structure. Additionally, the study highlights the role of fiber orientation on the multiple stable states within the corrugated shell structure. |
