Sheet Metal Rolling of Molybdenum: Thermo-Mechanical FEM Simulations

Abstract:

Metal forming simulations based on the finite element method are a frequently used tool for the prediction of the deformed shape, material state and reaction forces. The most critical prerequisite for any reliable result is a reasonable description of the constitutive behavior of the underlying material. The presented work focusses on the latter for the case of molybdenum via advanced formulations for the temperature and strain rate dependence. The quality of the results is compared for several approaches. Sheet metal rolling serves as an example application. Verification is based on comparison with data from industrial processes.
