摘要：Surface roughness is an important parameter that affects the fatigue life/ strength of a material. The effect of surface roughness on the fatigue life of Al 6160 alloy is investigated in the current research. Standard fatigue specimens are fabricated as per the requirement of the 25KN axial fatigue testing machine and tested for low cycle fatigue life. Specimens of three categories are tested for the fatigue life and the results are compared. Firstly, smooth specimen as per the standard is tested, followed by specimen with first grade of roughness, followed by the specimen with second grade of roughness. It is clearly evident from the test results that, as the surface roughness increases, the fatigue life decreases drastically.
