Abstract: The crankshaft is a critical element of internal combustion engines, extensively utilized in automotive applications.Fatigue failure represents the most prevalent mechanism of crankshaft failure.The experimental analysis focused on investigating the properties and characteristics of the material used in manufacturing the shaft for the ARO 244 vehicle.This research aimed to comprehensively evaluate the material's performance under operational conditions by examining its chemical composition, microstructural features, and mechanical behaviour.By understanding these attributes, the study sought to assess the suitability of the material for ensuring the durability, strength, and reliability of the shaft during prolonged use.The vehicle was manufactured at Brasov, having in the moment of failure more than 400,000 kilometers.The samples were analysed from microscopic, chemical, and mechanical perspectives.From a mechanical standpoint, the samples were subjected to bending, torsion, compression and resilience.
