抄録

Preliminary experiments of a wrapping fold membrane are performed to determine the fold properties for the packaging density and the effects of the plastic deformation on the layer pitch. To determine the packaging density, relationships between the layer pitch of the folded membrane and the contact force applied to the membrane are examined experimentally. Fold FEM analyses using stress-strain relationships which are determined by a one-dimensional fold model are demonstrated to investigate the effects of the plastic deformation. As the results of these analyses, the critical layer pitch which doesn't have the plastic deformation is derived.
