Abstract |
|
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. |
