In this thesis, the analysis of the variation of the k-factor after multiaxial loads in a uniaxial tensile test is done. For the performance of this project, the characterization of the DC04 steel is made, analyzing the steel by the strain of a first multiaxial deformation and of a second uniaxial tensile test not only mechanically, but also electrically on different geometry surfaces. In these geometries, a strain gauge is printed to measure electrically the strains of the deformation of the specimen and naturally also measured mechanically. These experimental measured systems are explained in this work as also the evaluation performed. The relation of the electrically measurement by the resistance of the strain gauge and of the mechanically measurement by the elongation of the specimen in a study range after multiaxial load is the aim of this work.
