Abstract |
Membrane's rigidity and state of the stress change greatly by the wrinkle. However, because the measurement example concerning load-displacement relation of the membrane material which is accompanied by the wrinkle generation by the experiment is few, an enough verification is not done. The low stress level is generated in the wrinkle which is accompanied by the shear though the wrinkle experiment in the past is a lot of the one done at a high stress level. Moreover, the rigidity is high and the change in the direction of the string according to the shear deformation is also large. And, experiments on the shear deformation of the membrane material in this study, the relation between the wrinkle generation and the rigidity change is examined, and whether an analytical technique by the stress transition method appropriately evaluates the wrinkle generation of the membrane material is verified. In addition, the problem after the wrinkle is generated is arranged, and a proper evaluation method is proposed. |
