Abstract:Failure analysis was performed on the light truck diesel engine crankshaft made of CK45 steel. Premature failure has been reported in the fillet zones of the main journal-to-crankpin. This study included chemical composition determination, macro and microstructural analysis, mechanical properties evaluation, fractography, and numerical analysis. Fractographic studies using the scanning electron microscope (SEM) identified fatigue as the main mechanism of crankshaft failure. Numerical results showed that the maximum value of stress has occurred in the crack initiation zone. The results of ...
