Abstract
The paper describes the study of influence of finite element form that is used for partitioning of rectangular strip in simulation of rolling process with the use of smooth rolls. The accuracy of determining of velocity in longitudinal direction has been analyzed at each point of the deformation zone. Simulation of the rolling process has been performed using the penalty functions method and ESVDeform software package that was developed at the Chair of Metal Forming of DSTU. The results of the analysis allow recommending the 3D finite elements of rectangular form for practical use. It grants high accuracy of velocities prediction. The tetrahedral elements have been recommended to use in the cases when the accuracy of velocities prediction is not very important, but a large uneven strain distribution is presented in deformation zone.
