Micrographs of metal surface layers after the roller burnishing process show that while about 90% of surface layer thickness is displaced forwards of a roller motion, a thin contact zone undergoes a backward displacement. This seizing effect is caused by a softening of the contact zone due to overheating of the material, during high speed rolling, or due to the plastic strain cumulation in the layer after multiple rolling repetition. The effect is responsible for a peeling and cracking of surface layers during the burnishing process. The plastic analysis of the process taking into account the above effect is presented in the paper. The proposed slip-line field and corresponding velocity field are modification of the simplified solution for the rolling of the rigid-plastic half-space given by Collins.
