Abstract

A continuum analyses for deployment characteristics of one-dimensional deployable membrane is formulated theoretically to investigate the nonlinear effects of creases. The structural properties of folded membrane affect the deployment characteristics, and thus, the existence of initial deformation/shape as creases should be precisely treated in the static and dynamic analyses. To investigate the effects of the initial configuration of membrane on the deploying, the theoretical and numerical analyses are performed in this paper. The large deflections analyses of beams with initial configuration is applied to the theoretical analyses to formulate one-dimensional deployment of membrane. The effects of geometrical nonlinearity due to the thickness and radius of curvature are considered in the analysis to examine the effects of creases, also, in-extension model is assumed in the analysis as Elastics. Some numerical examples are performed to investigate the effects of the ratio of thickness to radius on the deformation characteristics and the maximum bending stress induced in the membrane in the course of deployment The results show that the deformation of the membrane calculated by the proposed analysis is smaller and non-dimensional stress ratio calculated by the proposed analysis becomes larger for larger ratio of thickness to radius than the conventional membrane model using Elastics. Finally, the results indicated that the ratio between Hie membrane thickness and the radius of curvature affect the deployment characteristics.
