The mathematic calculation on two-body wear of austenitic manganese steel has been
performed by means of the elastic contact theory, stress interferometer and SEM.
Stress distribution in contacted area was calculated and the mechanism on two-body
wear has been investigated through numerical quadrature. Results show that two-body
wear is mainly plowing wear, the cracks of abrasive dust originates from the region
between 0.2® and 0.5® (® is radius of contacted round). Driving force to make crack
extension along y axis is ¿yzmax and extension direction is 45± with horizon. Driving
forces to make crack extension along x axis is alternative ¾x and ¿yzmax, the direction
of crack extension is 37。 with horizon.
