Research of TRIP Steel Mechanical Properties under Conditions of Plane Shear Stress

These days is still increasing emphasis put on making the production process of sheet metal stampings, which are used in the automotive, aerospace or power industries, more accurate and fast. These aspects need to be proportionately respected with respect to the economic side of these components production and in light of still increasing environmental requirements. This paper deals with the research of tested ultra-high strength steel mechanical properties under conditions of planar simple shear test (ASTM B831). The research of these properties is applied for ultra-high strength TRIP steel HCT690T EN 10346. In the experimental part was carried out plane shear tests to determine the basic mechanical properties and deformation characteristics of tested material. In the future research, measured data will serve as additional input material characteristics for numerical simulations, which can contribute to increase accuracy of computation for the given forming process.
