Compilation of a thermodynamics based process signature for the formation of residual surface stresses in metal cutting

The abrasive wear behaviour and fatigue life of many components in mechanical engineering depend on their surface stress states. Compressive surface stresses hinder ductile or brittle crack formation as well as crack propagation into the bulk material and therefore increase the lifetime of dynamical...
