Purpose: This paper contains a comparative analysis of the computer simulation results and calculation results on engineering techniques used to estimate the parameters of the stress-strain state, as well as the efficiency of FEM plate rolling process modelling application. Design/methodology/approach: Development of a computer model of the rolling process was carried out considering assortment of produced steel and technological capabilities of the plate rolling mill 5000 JSC „MMK” equipment. Findings: Analysis of the stress state in DEFORM-3D software showed that FEM-simulation of plate rolling does not give reliable data on the index of the stress state because they do not satisfy the boundary conditions at the input and output of the deformation zone. Research limitations/implications: Use of DEFORM-3D and Q-FORM software packages allowed to reveal patterns of inhomogeneous deformation change, stress state index, the velocity field on the geometric parameters and modes of deformation zone rolling. As a criterion of deformation inhomogeneity in the deformation area a coefficient of variation is used, which is convenient for analysis and forecasting quality of the structure during rolling. Originality/value: The work contains comparative analysis of the data received on the extent of the backward and forward slip zones, as well as according to the nature of the inhomogeneity of stressed and strained state while sheet rolling.
