dc.description.abstract Recent advances in space exploration call for smaller space structures that can be reconfigured to achieve large surfaces when in operation. Compact, lightweight structures that can be folded or coiled up for launch have been made possible thanks to self-deployable booms. These can then be self-deployed in orbit to support a variety of small spacecraft systems. However, prior understanding of deployment behaviour is important before launch. This study focuses on model reduction techniques in predicting the deployment behaviour of coiled long-narrow thin shells known as tape springs. Coiling, stowage, and deployment stages that demonstrate considerable crosssection deformation of the tape-spring are discussed. The developed numerical benchmarking model well agrees with the theoretical framework that has previously been established in terms of deployment time and stored strain energy. This numerical model has further been used in a stage-wise development of a beam-shell hybrid model. The effect of varying hub radius is introduced to the existing theoretical framework to predict the coiling and deployment behaviour more accurately. en_US
