Preliminary results concerning influence of polydispersity of ‘atomic’ sizes on elastic properties of the rotator phase of a three-dimensional system of hard dumbbells have been presented. It has been shown that, in contrast to two-dimensional hard discs and three-dimensional hard spheres, for the polydispersity parameter not higher than 5%, there is no significant influence on the elastic constants and Poisson’s ratio of hard dumbbells of the anisotropy parameter 0.15 (i.e., when the discs forming dumbbells are distanced by 15% of the average disc diameter).
