The contact side is in the complex stress state by the example of receiving the external force coming in contact the object each other and being used in engineering. It is assumed that these cause the surface damage by straightening, and generating extremely high contact pressure power in the vicinity of contact side. A static load is loaded to the disc where a part of crack exists, and then, the stress field in the point of contact neighborhood is analyzed, and examined experimentally in this research. Concretely, how parameters of the contact side obtained by the formula of the stress intensity factor obtained from an experimental analysis by a photodynamic technique and the hertz and the contact pressure, etc. exert the influence is considered to the crack parameter of the disk. A static load loaded by the lever equation loading device.
