“…In addition, the computations were limited either to the steady-state stage of the process or to the beginning of the forming process. Complete numerical models of the piercing process for thick-walled tubes taking into consideration thermal phenomena were constructed by several authors only in the last ten years [17][18][19][20][21][22][23][24][25]. The computations were performed with commercial simulation programs such as MSC.…”

Abstract. This paper presents the results of a numerical analysis of a helical rolling process for producing a 25 mm diameter workholding bolt using multi-wedge helical tools. The numerical modeling was performed by the finite element method (FEM) using the commercial simulation software Simufact.Forming v. 12. The modeling was performed in a three-dimensional state of strain and included a full thermal analysis. As a result, the changes in workpiece shape as well as the distributions of strains, temperature, damage, loads and torque were determined. The numerical results confirm that workholding bolts can be produced by multi-wedge helical rolling.

“…The above presented examples of the 3D numerical modelling of the piercing process did not include the models of material cracking. For the first time such model (compliant with Cockroft-Latham criterion) was applied in 2008 by Chastel et al [19]. The simulation, however, was limited to the initial forming phase and did not take into account the piercing plug.…”

The article presents a comparison of the piercing process conducted in a two-roll Diescher mill and a three-roll mill. The comparative analysis was based on the numerical simulations of the aforementioned processes, obtained using Forge NxT 1.1. software. It was stated that the most favourable manufacturing method is skew rolling in three-mill rolling mills. The mills operating in this scheme are less energy-consuming, whereas the manufacturing time is 30% shorter.

“…The modelling results were in good agreement with the experimental results. This method of modelling crack formation was later used in the analyses carried out by Chastel et al [6] and Ghiotti et al [7]. Other damage criteria have also been used in the analysis of the piercing process.…”

Determination of the critical value of damage in a channel-die rotational compression test

et al. 2019

This article describes the problems involved in modelling material cracking in skew rolling processes. The use of the popular damage criteria is impossible because of the lack of a calibration test that would make it possible to determine the critical value of material damage under conditions similar to those found in skew rolling. To fill this gap, a test called channel-die rotational compression was proposed. It consisted of rolling a disk-shaped specimen in a cavity created by two channels of cooperating tools (flat dies), which had heights smaller than the diameter of the specimen. When the rolling path was sufficiently long, a crack formed in the axial zone of the specimen. In this test, modelling using the finite element method made it possible to determine the critical values of material damage. As an illustration, the test was used to determine the critical damage value when conducting a rotational compression process on 50HS steel (1.5026) specimens formed in the temperature range of 950-1200°C. The analysis was conducted using the Cockcroft-Latham damage criterion.
