Development of a Predictive Pitting Life Model for Gear Teeth

将开发一种模型来预测接触表面(如齿轮齿)中凹坑的发展。该模型将基于基本面，并将取代目前使用的、基于经验的方法。该模型在裂纹萌生阶段考虑了夹杂物等微观结构因素，在裂纹扩展阶段考虑了断裂力学和粗糙面接触动力学。

A model will be developed to predict development of pits in contacting surfaces, such as gear teeth. The model will be based on fundamentals and will replace a currently used, empirically based approach. The model will incorporate inclusions and other microstructural factors in the pit initiation stage and fracture mechanics and asperity contact dynamics in the crack propagation stage.
