在材料科学中,拉胀行为是指拉伸时的横向加宽。我们调查的问题,发现在全球变形空间的周期性框架的auxeticity域。案例研究包括平面周期机构构造的四边形与对角线作为周期和其他框架的两个顶点轨道。我们涉及几个几何和运动学的描述。
In materials science, auxetic behavior refers to lateral widening upon stretching. We investigate the problem of finding domains of auxeticity in global deformation spaces of periodic frameworks. Case studies include planar periodic mechanisms constructed from quadrilaterals with diagonals as periods and other frameworks with two vertex orbits. We relate several geometric and kinematic descriptions.
