Abstract A continuum damage mechanics (CDM)-based approach is proposed to investigate fretting wear and fretting fatigue behavior of Ti-6Al-4V with the consideration of debris layer evolution. An elastic-plastic-damage model is developed to calculate the stress, strain, and fatigue damage fields. The debris layer and its thickness evolution are considered in a friction energy-based wear model. Both models are implemented in a finite element package to predict the fretting wear profile and fatigue lifetime. It is found that the numerical approach with the consideration of debris layer provides more accurate predictions than that without debris layer. The effects of debris layer evolution on the fretting fatigue lifetime, wear profile, contact pressure and subsurface stress are evaluated.

基于 CDM 的方法结合碎屑层演化用于微动疲劳的磨损和寿命预测

摘要 提出了一种基于连续损伤力学（CDM）的方法来研究Ti-6Al-4V的微动磨损和微动疲劳行为，同时考虑碎屑层演化。开发了弹塑性损伤模型来计算应力、应变和疲劳损伤场。在基于摩擦能的磨损模型中考虑了碎屑层及其厚度演变。两种模型都在有限元包中实现，以预测微动磨损曲线和疲劳寿命。发现考虑碎片层的数值方法比没有碎片层的数值方法提供了更准确的预测。评估了碎屑层演变对微动疲劳寿命、磨损轮廓、接触压力和次表面应力的影响。
