Effect of temperature on material behaviour in the tensile test
Original language description
In modern engineering, the possibility of predicting the behaviour of processed material by means of numerical simulation is increasingly used. Knowledge of this issue is important to ensure the stability of the pressing process. Achieving higher process stability leads to a reduction in the number of correction loops for forming tool optimisation, and lower production rejects, and time and financial savings in tool and die shops. However, with respect to increasing productivity, there is instability in the pressing process, which may be related to the material’s behaviour when the deformation rate changes. There is a change in tool temperature due to friction between the tool and the material and heating of the material due to deformation. Therefore, it would be interesting to see whether the mechanical properties of the material change with temperature. The thermal effects in the cold-forming process should be implemented in the numerical simulations. This work aims to carry out a heating design that will allow heating to temperatures corresponding to those of the pressing process. The specimen should be visible for the possibility of deformation analysis, e.g. by the ARAMIS system, which works on the principle of digital image correlation. The functionality of the designed device will be tested in tensile tests. Different temperatures from ambient to 160 °C will be measured to cover the continuous heating process in real forming.
