PHYSICAL MODELLING AND NUMERICAL FINITE ELEMENT METHOD (FEM) SIMULATION OF FORGING IN OPEN DIE OF ALLOY AIMgSi0, 5

This paper researches the process of forging in open die of gradual axial-symmetric workpiece made of alloy AIMgSi0, 5. The physical modelling was carried out, for which an original method for physical discretisation and numerical FEM analysis was developed. The components of tensor were determined: strain, strain rate, stress and the corresponding effective parameters. The results obtained experimentally and through a numerical FEM simulation were compared and analysed.
