On the straining of metals along the plane curvilinear paths of variable curvatures. report 2. process functions

摘要

This paper presents and analyzes the results of the experimental investigations on complex loading and unloading of 45 steel along the paths such as the Archimedean spiral in the plane Э{sub}1-Э{sub}3 of the Ilyushine deviatoric subspace ofstrains Э{sub}i (i = 1, 2, 3) which were carried out using the model SN-EVM computer-aided calculation-and.. experimental system. The experimental regularities of variation in the constitutive functions of plasticity have been obtained which areconstructed in the framework of the Ilyushine hypothesis of coplanarity.
