A compression test specimen is arranged as a cylinder with opening and circular collar with varying thickness in its perimeter at its one end surface, at that the axis of the opening is displaced with respect to the axis of the cylinder by value of half of difference of maximum and minimum thicknesses of the collar. Similar circular collar with varying thickness in perimeter of the opening is arranged as supplementary one on the second end surface of the cylinder, at that the opening of the supplementary circular collar is placed coaxially with respect to the opening of the cylinder and its main circular collar. |
