This paper investigates a three-dimensional finite element model for the cross-wedge rolling process has been used to characterize the workpiece material stress and deformation behavior. Considering the characteristic of cross wedge rolling, the static implicit FEM program is selected. To simulate all forming stages in the cross wedge rolling process, dynamic adaptive remeshing technology was applied. Examples of numerical simulation for strain, stress distributions and rolling load components have been included. The stress distributions in the cross-section of the forming workpiece are analyzed to interpret fracture or rarefaction at the center of workpiece. The computer codes in finite element method can be used for a large variety of problems by simply changing the input data.

Abstract This paper presents results of numerical calculations for the rolling process by means of three tools of stepped shafts from aluminum alloy 7075. Forming with the usage of tools with three different wedge spreading angles underwent analysis. In the paper, the obtained distributions of stresses, strains and Cockcroft-Latham damage criterion were given. Moreover, the influence of the wedge spreading angle on shape faults presence in the obtained product was determined. At the same time, the force parameters, which play a crucial role in the designed experiment, were analyzed.

This paper investigates the interfacial slip between the forming tool and workpiece in a relatively new metal forming process, cross-wedge rolling. Based on the finite elements method, three-dimensional mechanical model of cross wedge rolling process has been developed. Examples of numerical simulation for strain, stress distributions and rolling load components have been included. The main advantages of the finite element method are: the capability of obtaining detailed solutions of the mechanics in a deforming body, namely, stresses, shapes, strains or contact pressure distributions; and the computer codes, can be used for a large variety of problems by simply changing the input data.
