Cumulative Fatigue Damage

Shot peening process has both the beneficial and detrimentaleffects; therefore, it is difficult and time–consuming task to determine the optimized process parameters based on the fatiguelife. In this study the fatigue of 7001-T6 high strength aluminum alloy has been investigate before and after a shot peeningis beneficial for a treatment to investigate where a shot peening is beneficial for a component with this combination. The effect of 12 min. shot peening on the fatigue behavior of the material used gave an increase in the fatigue life of up to 2.49 times depending on the applied stress, and a 28.34% increase in the endurance limit of the material. Cumulative fatigue damage was conducted under low-high and high-low stress amplitude .The fatigue life prolonging factor (FLPF) was calculated for different stress amplitudes and it was found that this parameter is an indicator for prolonging the fatigue life.

The Impact

The paper handles the fatigue and failing analysis of serial shot-peened leaf springs of cumbersome vehicles emphasizing on the impact of shot peening on fatigue life, coping with automotive leaf springs, the shot peening method turns into an important step in production.In the situation of leaf spring suspensions, however, asystematic research of the effect of shot peening about fatigue life isstill required. Experimental stress-life curves are determined with the aid of the usage of investigating clean specimen subjected to shot peening. those test consequences are as compared to corresponding ones identified from cyclic three-point test on shot peened serial leaf springs in order to show the influence of applied heat treatment and shot peening approach on fatigue existence of high-strength used to get leaf spring manufacturing, reliant on the load level. Analyses are performed to explain the effects resulting from shot peening practice on the surface features of the high-strength spring steel under examination. The evaluation of fatigue results shows that almost no life improvement due to production highlighting the importance for mutual variation in parameters of shot peening and thermal treatment so that there is sufficient progress in life
