The process of inducing compressive stresses relies on the impact of high velocity shot onto the target material surface. The impact of these shots lends to make the surface rougher and results i Experimental and numerical investigation on shot peening of low alloy steel n the formation of local stress concentrations which can be a precursor to fatigue failure.

ch is defined as the percentage of the sum of peened area over the total area on the surface of the specimen. A new method with the aid of Matlab™ codTECHNOLOGICAL UNIVERSITYSINGAPOREEXPERIMENTAL AND NUMERICAL INVESTIGATION ON SHOT PEENING OF LOW ALLOY STEELPHAM QUANG TRUNGSCHOOL OF MECHANICAL AND A Experimental and numerical investigation on shot peening of low alloy steel peening process was further dev eloped using experimental results for increased accuracy. The numerical and experimental studies give a good agreement in the compared results in the topography and surface roughness of the shot peened steel. As a result, after validating the FF.M model with the expe Experimental and numerical investigation on shot peening of low alloy steel rimental results, the FF.M mcxlel can be used to predict the results for the other shot peening conditions (same material) as well as provide the initExperimental and numerical investigation on shot peening of low alloy steel

The fatigue tests revealed that the shot peening process could significaTECHNOLOGICAL UNIVERSITYSINGAPOREEXPERIMENTAL AND NUMERICAL INVESTIGATION ON SHOT PEENING OF LOW ALLOY STEELPHAM QUANG TRUNGSCHOOL OF MECHANICAL AND A Experimental and numerical investigation on shot peening of low alloy steel revalent under higher peening pressures and led to aivreduction in the fatigue life. Therefore, to maximize the performance of the process, the peening parameters need to be carefully selected.
