This paper presents a finite element model to simulate the teeth failure of noncircular composite chainring. Model consists of the chainring and a part of the chain. To reduce the size of the model, only the first 11 rollers are simulated. In order to validate the model, it is firstly applied to a circular aluminum chainring and evolution of the stress in the teeth is compared with the literature. Then, effect of the noncircular shape is studied through three different loading positions. Strength of noncircular composite chainring and failure scenario is investigated. Moreover, two composite layups are proposed to observe the influence of the stacking. Results show that composite material can be used but the layup has a large influence on the strength. Finally, loading position does not have influence on the first composite failure that always occurs in the first tooth.
