Poisson's ratio in chiral Cosserat elastic solids is considered. Chirality allows the Poisson's ratio to exceed classical bounds, even if the material is directionally isotropic and all elastic moduli are within thermodynamic limits based on strain energy density. Poisson's ratio in chiral rods depends on the chiral elastic constants as well as on the shear and bulk moduli, assumed positive. Poisson's ratio can be greater than 0.5 or smaller than −1 for slender chiral specimens.

手性各向同性弹性材料中的扩展泊松比范围

考虑了手性 Cosserat 弹性固体中的泊松比。手性允许泊松比超过经典界限，即使材料是方向各向同性的并且所有弹性模量都在基于应变能密度的热力学极限内。手性棒中的泊松比取决于手性弹性常数以及剪切和体积模量，假设为正。对于细长的手性样本，泊松比可以大于 0.5 或小于 -1。
