A method for testing circular samples of tubes with tension includes preparation of sample, placement of the sample on two holders with circular cross section with same diameters with parallel axes and deformation through bringing the holders aside till break. First deformation is carried out till the sample takes the form of elongated ring, after that deformation is terminated, curvilinear parts of the sample are pressed to the surface of the holders to exclude slide, and the sample is cut at one side at linear section, and then deformation is continued. |
