Fracture of an Automobile Anti-Roll Bar

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 a failed anti-roll bar of an automobile is carried out. The analyzed type of the anti-roll bar is especially important as many cases are reported about the fracture after 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 assess 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. The authors conclude that the fracture took place after a fatigue procedure under a combined bending and torsional stresses that have a highly reversible nature; the crack of the fracture is initiated at the highly stressed region of the bar; the fracture took place in a ductile manner; and the production process could have affected the initiation region of the failure.
