The International Journal of Advanced Manufacturing TechnologyAbstract The purpose is to research the effect of different shot peening parameters on the fatigue life of double-sided shot peening of SAE1070 steel. The method that in this paper, establishes a DE-FE (Discrete element-finite element) random multi-shot analysis mode is firstly used to simulate the processing of double-sided shot peening on ...

Development of a Wöhler-like approach to quantify the Ti(CxNy) coatings durability under oscillating sliding conditions [PDF]
, 2005 The selection of a proper material for the particular engineering application is a complex problem, as different materials offer unique properties and it is not possible to gather all useful characteristics in a single one. Hence, employment of different
