以GH4169镍基高温合金为研究对象，基于低周疲劳率相关的晶体塑性本构，引入累积能量耗散和累积塑性滑移2种疲劳指示因子作为疲劳裂纹萌生判据，对不同微缺口深度和长度下的疲劳裂纹萌生寿命进行研究。并基于统一拘束参数Ap，进一步考察拘束与疲劳裂纹萌生寿命的关联。结果表明：2种疲劳指示因子均可较好地预测疲劳裂纹萌生寿命。随着微缺口深度的增加，疲劳裂纹萌生寿命逐渐减少；随着微缺口长度的增加，疲劳裂纹萌生寿命逐渐增加。在不同的微缺口深度和长度下，疲劳裂纹萌生寿命均与

Nickel-based GH4169 superalloy is used as turbine disc material in aeroengines because of its good oxidation resistance, good formability, weldability, and high strength. However, turbine disc fatigue failure will inevitably occur in onerous service environments and after a long operation time. To ensure the safety and reliability of aeroengines, the fatigue damage behavior and fatigue life of GH4169 superalloy need to be studied. Constraint is an important factor affecting the fatigue fracture behavior of materials, because changing it will impact the fatigue behavior. To achieve a long service life and high reliability of aeroengines, fatigue and constraint effects must be researched. However, there are only limited studies on the effect of constraint on fatigue crack initiation time. In this study, a crystal plasticity constitutive model based on low cycle fatigue rate correlation was applied to the GH4169 superalloy. Two fatigue indicators, namely the cumulated energy dissipation and cumulated plastic slip, were introduced as fatigue crack initiation criteria to study the fatigue crack initiation time for different micro-notch depths and lengths. In addition, the relationship between constraint and fatigue crack initiation life was further investigated using the unified constraint parameter Ap. The results showed that both cumulated energy dissipation and cumulated plastic slip can accurately predict the fatigue crack initiation time. With the increase in micro-notch depth, the fatigue crack initiation time decreased, while it increased with the increase in micro-notch length. A linear relationship between the fatigue crack initiation time and
