This study was conducted to determine the stress in sports car camshaft using the finite element method. The simulation was based on three conditions which include flawless, wear defects, and wear with initial defects such as early cracks. The results showed that the maximum normal stress in the model without defects was 7.8 MPa at the fillet area, while the stress in the worn model was 22 MPa. These values were below the material permit limit of 29.8 MPa. Meanwhile, the worn model with initial defects such as cracks had 252 MPa, and this exceeds the limit. It was also observed that the stress intensity factor at the crack tip was 17.9 MPa m1/2, and this indicates a propagation crack. Therefore, it was concluded that camshafts without defects or with wear and tear are safe to use, while those worn with defects such as cracks are not. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
