分析了加载频率ｆ对腐蚀疲劳裂纹增长的影响，提出了一种计及加载频率ｆ影响的腐蚀疲劳裂纹增长数学模型ｄａ／ｄＮ－（ΔＫ，ｆ）
A lot of experiments have indicated that the loading frequency f is one of the improtant factors that affect the fatigue crack growth rate under the corrosive environment.So both microeffects and macroeffects of loading frequency f on the corrosion fatigue are studied by experiment research and theoretical analysis.And a mathematical model of corrosion fatigue crack growth rate da/dN-(ΔK,f) is derived.This mathematical model will make it possible that the corrosion fatlgue crack growth rate of aeronautical materials and service life of aeroplane under corrosive aneironment are determined by computer simulation.
