Description: An elastic-plastic finite element analysis of the quasi-static loading of two acetal copolymer gears in contact is preformed. Load verses rotation of the gear set is compared to actual experimental results. The gear geometry is modeled by plane strain elements with variable thickness between the rim and web. Gear tooth failure is modeled by both deactivating and separating elements when the tensile strength is exceeded. Failure in the tooth root is best modeled by a nonlinear approach using separating elements.
