Abstract
To obtain fundamental data for research on surface durability of contacting bodies, contact stress between rollers with surface roughness or pit is analyzed. The increasing degree of contact stress owing to surface roughness is given by a non-dimensional factor, which is the ratio between maximum surface roughness and geometrical interpenetration of the contacting bodies. The contact stress concentration around a triangular pit is also discussed.
