Theoretical and numerical analyses of engineering elastic characteristics (Young’s modulus and Poisson’s ratios) of cylindrically anisotropic tubes formed by rolling-up plates of cubic crystallographic structures (110) and (111) are given. Present results are compared with the results for tubes with crystal structural orientation (001), studied previously. It is found that tubes with (110) crystal structure exhibit auxetic properties (negative Poisson’s ratio) more often. Poisson’s ratios averaged over the cross-section of some tubes have negative values.

通过卷起各种取向的立方晶体板获得的手性管的拉伸

给出了由立方晶体结构(110)和(111)的卷板形成的圆柱各向异性管的工程弹性特性(杨氏模量和泊松比)的理论和数值分析。目前的结果与先前研究的具有晶体结构取向 (001) 的管的结果进行了比较。发现具有(110)晶体结构的管子更常表现出拉胀特性(负泊松比)。一些管子横截面的平均泊松比具有负值。
