“…However, because of its nonlinear nature and its complex condition, it is very important to consider it particularly. Combining the finite element and boundary element methods, Shangwu et al (1999) carried out the 3D modeling of hot rolling process of flat strips. They predicted rolling force, rolling torque and contact pressure on the roll for both rigid and flexible roll cases.…”

“…The first category includes thermo-mechanically coupled models that allow the hot rolling process to be simulated very accurately, for predicting with tight tolerances the final shape of rolled product, its metallurgical structure or several rolling parameters. Some examples are given in the previous studies, [3][4][5][6][7][8][9][10][11][12][13][14][15][16] just to cite a few (a detailed review is beyond the scope of this article).…”

“…These coupled models (especially 3D) thus provide a very realistic representation of the rolling process, although at the expense of a high computational cost. For this reason, improved modelling approaches and solution strategies, ranging from mixed analytical/ numerical methods, 6 finite element models [3][4][5]7,8,10,11,[13][14][15][16] or combined finite elements/boundary element formulations, 9 have been devised to alleviate the computational burden required by such complex numerical models.…”

This work presents a one-dimensional harmonic finite element for the transient elasto-plastic analysis of axisymmetric structures loaded by non-axisymmetric thermal and mechanical loads. The one-dimensional element exploits a semi-analytical approach, based on Fourier series decomposition of the applied loads. The initial stress method is used for the non-linear solution of elasto-plastic analysis. As a case study, the proposed one-dimensional harmonic element is applied for modelling a two-dimensional circle under thermal and mechanical loadings rotating over its surface, which is used as an approximation of a work roll in hot strip rolling. With the one-dimensional harmonic element, the cyclic thermo-mechanical behaviour of the work roll can be simulated by considering localized plasticity caused by thermo-mechanical loads representative of strip and back-up roll. Compared to two-dimensional models already used in the literature, the one-dimensional element allows a significant reduction in the computational time to be achieved; it follows that the whole transient thermo-mechanical response can be simulated, thus permitting a more complete evaluation of the stress-strain response that is necessary for fatigue life assessment. © IMechE 2016

“…Kim, Lee, Shin, and Shivpuri (1992) investigated shape rolling process using computer software, TASKS, based on the finite slab-element method and their predicted roll force and torque indicated reasonable agreement with other published results. Combining the FE and boundary element methods, Shangwu, Rodrigues, and Martins (1999) carried out the three-dimensional (3-D) modeling of hot rolling process of flat strips. They predicted rolling force, rolling torque, and contact pressure on the roll for both rigid and flexible roll cases.…”

Accurate prediction of the roll separating force and roll torque is critical to assuring the quality of the product. Fluctuation of these parameters during the rolling process is even more important because of its effects on rolling setups, geometrical accuracy (especially flatness in strip rolling), and the uniformity of mechanical and microstructural properties of the rolled material. The main approach of the present study is a precision analysis of the roll force and roll torque and their instabilities during the rolling process. In doing so, a coupling multi-variable simulation model for hot strip rolling was built using non-linear thermo-viscoplastic finite element method. Fluctuations of roll force and torque about the steady-state operating point are derived and the effects of main process parameters such as rolling speed and strip reduction on these instabilities are investigated. To check the validity of the employed model, predicted results are compared with experimental data.
