Аннотация

The article considers the task of improving the technological properties of a material in order to improve the ultimate deformation under the action of tensile normal stresses. The solution of this problem is based on the model of anisotropic hardening by G. Backhouse. The necessary ratios have been obtained to optimize the process of improving the technological properties of the material. In order to experimentally verify the obtained solution to the problem under consideration, experiments were performed on thin-walled tubes under conditions of loading them in the tension-torsion – tension cycle, confirming with an accuracy of less than 90% the possibility of using the proposed method of increasing critical deformation in production conditions.
