Investigation of corrosion fatigue cracks of steel under wetting and drying conditions

Abstract

The results demonstrated that dry/wet ratio and loading frequency could significantly affect the growth rate of the corrosion fatigue cracks of steel structure. The effects of dry/wet ratio on the growth rate of cracks became smaller with the increase of the amplitude of stress intensity factor under the same loading frequency. The effects of dry/wet ratio on the growth rate of cracks became smaller with the increase of loading frequency under the same dry/wet ratio.
