Nowadays, the tendency to survey and accelerate technological processes in order to increase produc-tion efficiency on the one hand and to reduce the ecological impact of production on the environ-ment on the other hand is increasingly prevailing. These aspects encourage both the applilcation of mathematical modelling of production processes and utilization of new material types ensuring suffi-cient strength and ductility while reducing the overall weight of the final asembly. This paper focuses on investigation and evaluation of the mechanical properties of the material under plane shear stress conditions. Specifically, it concerns the testing of a dual-phase high-strength steel DP500 (designa-tion according to EN 10346) having structure based on a ferritic-martensitic matrix. The test material is loaded by means of a testing machine with a continuous static load and condition of the plane shear stress is achieved due to the geometry of the test specimen (ASTM B831). In the experimental part of this paper, plane shear tests are performed to determine the basic mechanical properties and stress-strain characteristics of the material with respect to the given loading conditions. These deter-mined parameters and material characteristics can be further used as important input data to improve results of the numerical simulations regarding the aspect of metal forming technologies – basically stamping process.
