    The research focuses on the yield point definition and its effect on the deformed shape of yield surfaces during different stages of combined tensile and torsional load. Innovative applications of experimental techniques such as the acoustic emission and the electric potentials are used for an acquisition of yield inception and plastic straining. It is showed that the yield point definition plays an important role in calibration of material parameters. The cross-over of the yield point definition aspect in the context of calibration procedures and numerical implementations is commented as well. The ABAQUS FE-code with its UMAT routine is chosen for the finite element implementation.
