Rough contact between elastically and geometrically identical curved bodies.

Surface and subsurface stesses and displacements are obtained when two geometrically and elastically identical rough bodies were pressed together by normal and tangential loads. The theories of Cattaneo and Mindlin, who introduce zones of slip and stick within an elliptical contact area, are used. Von Mises yield criterion and maximum principle tensile stresses are used as failure criteria to assess potential failure due to shear to brittle fracture. (A)
