Abstract—In this study, the drive shaft failure mode in a van is investigated by evaluation of the macroscopic and microscopic morphologies of the fracture surface, chemical composition, metallographic analysis, mechanical characteristics of the material, drive shaft fatigue test and finite element analysis. JIS-S45C hardened medium-alloyed steel was used to make the drive shaft. The failure mechanism for this drive shaft was mixed, which means that it was a combination of both brittle and ductile fractures. This is evident in the central interior region of the drive shaft. The summary result of this drive shaft fracture surface was that fatigue was the cause, and fatigue was the dominant mechanism of drive shaft failure due to obvious beach marks at the fracture surface and dimples at the central region. The shaft surface has a maximum hardness of 300 HV, while its centre axis has a minimum hardness of 214 HV. Additionally, the results of the R.R. Moore fatigue life assessment were compared with the outcomes of the numerical simulations performed using the ANSYS program. It was found from the fatigue experiment that the S-N Curve shows that fatigue life increases when the stress level acting on the test piece is reduced. It was discovered that the ANSYS assessment rate was a respectable 5% higher than the trial rate. The results of recommending materials used to make shafts for all 4 types found that the total deformation for AISI 5140 Steel is less when compared to the other three materials.
