In this work a series of analysis concerning the behaviour of structures typically used in space applications are carried out. These structures are united by their properties of lightweight and very low thickness, along with the need for them to occupy an highly confined space; this last necessity makes the deployable structures the most acceptable solutions in the space industry. The numerical analysis of this kind of structures are carried out by means of two different codes: the commercial software Abaqus, and the Mul2 code developed by the homonymous group of the PoliTo, based on the CUF theory. The objective of this work is therefore to introduce the main features of the deployable structures, and then to demonstrate the ability of the Mul2 code to reproduce very reliable results for different kind of analysis and structures.
