Research Abstract

The elastic deformation model of 2D flexibly jointed structure was developed from the view of rotational interactions of joints to widely understand the deformation modes of spatial structures. Based on our developed model, we targeted some problems with the buckling bifurcation of square cells and the variable properties of Possion's ratio of novel structures, and we made clear the deformation mechanism of spatial structures that depended on the rotational characteristics of joints. We also evaluated the obtained numerical results by comparison with uniaxial stretching test, and we invented a newly developable structure by extending our proposed structural model.
