NUMERICAL SIMULATION OF CROSS ROLL STRAIGHTENING PROCESSES
Original language description
This paper summarizes the effort made in numerical simulation of cross roll straightening processes in tube straightening machines. Even though the theory of sophisticated material models for cyclic plasticity and cyclic viscoplasticity has made great progress over the last two decades, reports on numerical simulations of straightening process are quite sparse. Here, Chaboche model as a typical representative of material models for cyclic plasticity is briefly presented. Its main parameters were obtained by fitting the numerical results to the record of a specifically designed cyclic bending experiment. The predicted response was in good agreement with the measured data and hence the applicability of this constitutive model on tube straightening was validated. Chaboche model with the determined parameters was then utilized in the simulation of straightening process in a six-roll straightener. The resulting history of reaction forces in each roll provides a reasonable start point for th
