  • ABSTRACT: This article presents the outcomes from finite element (FE) simulation of the diamond burnishing of rail-end-bolt-holes. A reliable 3D FE model of the studied process has been developed with a view to fundamental understanding of the residual stress formation. The introducing of beneficial residual circumferential normal stresses around the treated hole closes the existing cracks and impedes the formation of new ones and thus enhances the fatigue life of the rail road.
