Model-based determination of nonlinear material parameters of metals with low melting points

An alternative way of determining the temperature-dependent characteristics of metals is presented. The method that is relatively simple and cheap is suitable mainly for metals with lower melting points. The paper starts with the experimental investigation of the melting process of the Field metal in an induction furnace, which provides all necessary information for determining the above material characteristics. These data are then used for a coupled numerical simulation of the process of heating and melting and also for sensitivity analysis and model-based determining of specific heat capacity. The results are again verified by measurements, with a very good agreement.
