Outline of Final Research Achievements |
In this study, through the application of the analysis using a generalized inverse matrix, whose validity has been confirmed for unstable linkage models, to a rigid origami model that is composed of panels and hinges, we investigated the characteristics of a rigid origami model at a singular state, and showed an example of the application of rigid-foldability condition to structural analysis. At first, for the compressive strength calculation for a square pipe as an example, we presented a way of applying rigid-foldability condition to yield line analysis. Next, for a singular state of a rigid origami model, we formulated the constraint condition in consideration of high order term and validated with some crease patterns.
