Berufliche Fachrichtung Agrarwirtschaftor this because, provided that folding does not involve a significant amount of mid-surface stretching, the stresses due to bending can be made as small as required to avoid yielding of the material, by choosing a sufficiently small thickness for the shell. Two examples of this “new” type of deployable structures will be discussed in this chapter.
