    Utilization normal vectors for description of fracture surfaces

  • Original language description

    Fracture surfaces generated under biaxial fatigue (combined bending-torsion loading) was studied presented work. Complexity of the crack path was characterized by normal vectors of elementary flats instead classical roughness parameters (such as arithmetic roughness etc.) or fractal characteristics used in previous studies. Presented method of description is based on normal vectors (or directional angles) and it was designed in order to overcome some disadvantages of old methods. Disadvantages that are typical for surface assessment using classical roughness parameters classical roughness parameters. This method applied on fracture surfaces generated by fatigue. These specimens were made from steel EN 37CrA1Mo 6. In experiments two sets of specimens were used, virgin and specimens with plasma nitrided surface. Description of the fracture surface using normal vectors, resp. their directional angles make it possible to describe the surface as well as by using classical roughness parameters. However, it does not require such a precise selection of the studied profiles. In addition, however, it allows some mapping of the direction of crack propagation.
