Abstract
Superficial laser treatments are currently used to generate hard metallurgical structures and compressive residual stresses on the surface of the component treated. This paper presents a three-dimensional numerical simulation of such a treatment, based on a computation of the thermal, metallurgical and mechanical steady state in the laser’s comoving frame. This simulation notably shows that very high tensile stresses are generated below the external compression zone; this result yields important consequences upon fatigue crack initiation and propagation.
