Abstract

In the development of the Self-deployable Deorbiting Space Structure (SDSS) [1][2] FEA are used to determine the stress state during the folding process of a given rectangular Highly Flexible Frame (HFF). The rectangular HFF is the load carrying structure in the SDSS. The stress state changes during the folding process of the HFF and this paper will determine the critical stress states. One of the important subjects in the stowed SDSS is the amount of stored strain energy in the HFF, and the amount of strain energy causes the pretension of the SDSS. To determine the pretension and stress stiffening in a given HFF, non-linear geometrical FEA are conducted.
