Conclusions

  1. 1.

    The not earlier noted fact of formation in contact impact on the surface of hardened steel of prismatic and segment chipping fragments was established experimentally. The first are formed in intersection of median cracks and the second in intersection of median and circular cracks.

     
  2. 2.

    Simple models based on criteria of fracture mechanics and low-cycle fatigue making it possible to analyze the forms of failure considered are proposed. Using the calculation relationships it is possible to determine the order of magnitude of the separate fragment.
