Construction of flexibly jointed structure with variable flexibility

为了广泛理解空间结构的变形模式，从关节旋转相互作用的角度出发，建立了二维柔性关节结构的弹性变形模型。基于我们开发的模型，我们针对方形单元的屈曲分岔和新型结构泊松比的可变性质的问题，明确了依赖于关节旋转特性的空间结构的变形机制。我们还通过与单轴拉伸试验进行比较来评估所获得的数值结果，并通过扩展我们提出的结构模型发明了一种新开发的结构。

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.
