Hinged lattices are envisaged with Sarrus linkages in the ribs and with rigid nodes where the ribs intersect. Triangulated lattices with Sarrus hinged ribs only deform volumetrically and have a Poisson’s ratio of −1. Lattices containing squares and hexagons can deform axially as well as volumetrically. All the lattices are compliant with respect to tension and compression and rigid with respect to bending. The lattices exhibit extreme Cosserat elasticity corresponding to rotational elasticity.

带有 Sarrus 链接的 Extreme Cosserat 弹性铰链格子

铰接格子被设想为在肋中具有 Sarrus 连杆，并且在肋相交处具有刚性节点。带有 Sarrus 铰链肋的三角网格仅发生体积变形，泊松比为 -1。包含正方形和六边形的晶格可以轴向和体积变形。所有的格子在拉伸和压缩方面都是柔顺的，在弯曲方面是刚性的。晶格表现出对应于旋转弹性的极端 Cosserat 弹性。
