Anti-roll bar is a suspension element used at the front, rear, or at both ends of a car that reduces body roll by resisting any unequal vertical motion between the pair of wheels to which it is connected. In this study, fracture analysis of an anti-roll bar of ab automobile is carried out. The analysed type of the anti-roll bar is especially important as many cases are reported about the fracture after a 100,000 km of travel. Mechanical characteristics of the material are obtained first. Then, the microstructure and chemical compositions are determined. Some fractographic studies are carried out to asses the fatigue and fracture conditions. A stress analysis is also carried out by the finite element technique for the determination of highly stressed regions on the bar. As a characteristic of the fatigue fracture, there are two regions in the fractured surface. These are a smooth surface created by crack propagation and a rough surface created by sudden fracture. As a conclusion, the following statements can be drawn: The fracture is taken place after a fatigue procedure under a combined bending and torsional stresses having highly reversible nature. The crack of the fracture is initiated at the highly stressed region of the bar. The fracture is taken place in a ductile manner. The production process could have affected the initiation region of the failure.
