Even in a macroscopically 2-dimensional contact situation, existence of surface roughness causes a 3-dimensional stress field in the vicinities of asperity contacts. Although several methods for stress analysis in the contact of rough surfaces have been established so far, the possibility of analysis was limited to the cases of 2-dimensional asperity contact or macroscopically 3-dimensional contact in which contact area is comparatively small. In order to elucidate the mechanism of pitting or rolling fatigue, it is necessary to develop a method of calculation of the 3-dimensional stress field near the asperity contact, which would occur in contact of cylindrical bodies having surface roughness. In this study, one method of such analysis is shown. This method can be applied to calculate the stress intensity factor of a crack in rolling contact of rough surfaces. which will be presented in another paper.
