Abstract

In this study, a method based on mathematical modeling was developed to determine the optimal technological parameters of the cold rolling process using symmetric technology in areas of deformation that are not canonical. This approach was proposed in order to study the stress-strain state in the active zone of elastic-plastic deformations of a metal strip. To test the effectiveness of this approach, the problem of cold rolling of an aluminum strip is considered. As a result of the solution, it is shown that when using the proposed approach, the stress intensity surface does not exceed the condition of the theory of small elastic plastic deformations by A.A. Ilyushin.

Keywords:

cold rolled materials, theory of rolled materials in displacements, stress-strain state of rolled materials, symmetrical and asymmetric rolled materials, plasticity function
