Abstract:
Mechanical pre-stressing treatments using shot peening are widely used in automobile, aeronautic and biomedical industries to improve mechanical parts and
structures. These cold-working processes use spherical media called shot, and introduce surface compressive residual stresses that are found to enhance the fatigue resistance of intermediate- and high-strength metals and alloys.
They protect the structure from fracture as fatigue cracks propagates mostly from surfaces during operation. The gain in strength and fatigue life observed after such a treatment can be spectacular while offering the advantage of being
relatively easy to perform technically.
