The article presents the results of a study of the stress-strain state of workpieces after severe plastic deformation performed in a closed die. The stress state study was performed by the slip lines method and in the Deform 3D simulation software. The analysis of the stress state shows that the value of the stress components within the workpiece increased after one cycle of deformation by 1.5 - 2.5 times. The prevalence of compressive stresses contributes to metal structure refining via high-cycle alternating strain.Keywords: Stress state; severe plastic deformation; numerical simulation; FEM
