Abstract
Using the COMSOL MULTIPHYSICS software, the problem of the stress-strain state of a steel wire during drawing is solved by the finite element method. A special contact layer is introduced to describe the contact between the wire and the matrix. It consists of a material whose modulus of longitudinal elasticity in the direction perpendicular to the contacting parts coincides with the modulus of longitudinal elasticity of the matrix or wire, and in the other direction is small, as is the shear modulus. During the calculation, the fields of radial stresses, axial stresses and equivalent stresses are obtained. The results of solving the problem allow us to proceed to the study of residual stresses after drawing, as well as to study the influence of various drawing parameters on the stressed state of the wire.
