Mathematical model of warm drawing of MgCa0.8 alloy which considers the ductility of the material

The results of experimental research analysis of MgCa0.8 magnesium alloy were presented in the present paper. Basing on experimental tests the flow stress function and the dependences among ductility strain, triaxity factor, temperature and strain rate were obtained. Experiment was performed by using the strength machine Zwick Z250. The algorithm based on inverse method was used to interpret correctly the experimental results. The FEM modelling of upsetting and tension tests were helpful to obtain conditions of material fracture phenomena. The developed models of mechanical properties were implemented into Drawing2d FEM code. The introduced approach is helpful to model the drawing process in high temperature and with respect to fracture criterion.
