Validation of a purely elastic model and a finite element model for a screw press

Abstract: The increasing use of superalloys in the industry brings new issues to forging manufacturers concerning Finite Element analysis of the forming process. Once we consider high performing materials, significant differences can occur between numerical and experimental results. The lack of knowledge about materials and thermal exchanges explains a part of these differences but it has been shown that the machine behavior has a significant impact on the forging process. Press modelling is a way to quantify the energy… Show more

“…The obtained results [11] were used to determine the modal parameters and calculate the scaling coefficients. In this study [17], the force-deformation curves of sunflower seeds were investigated under different presses. The objective was to determine the pressure and energy along the pressing chambers.…”
