Thanawarothon and L. Mezeix}, country = {}, institution = {}, abstract = {This paper presents a finite element model to simulate the teeth failure of non-circular 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 non-circular shape is studied through three different loading positions. Strength of non-circular composite chainring and failure scenario is investigated. Moreover, two composite lay-ups are proposed to observe the influence of the stacking. Results show that composite material can be used but the lay-up 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. }, journal = {International Journal of Materials and Metallurgical Engineering}, volume = {12}, number = {1}, year = {2018}, pages = {17 - 22}, ee = {https://publications.waset.org/pdf/10008527}, url = {https://publications.waset.org/vol/133}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 133, 2018}, }
