Durability improvement of axle housings by compressive residual stress inducement

This paper deals with durability improvement of axle housings used in a typical commercial vehicle by inducing surface compressive residual stresses to overcome the failure before acceptance. Analysis reveals life enhancement up to 88% at the failure location. Fatigue life estimates is more influenced by the mechanical strength of the material used for axle housings. However, the strength of housing material is altered by the manufacturing...
