Growth and retardation of physically short fatigue cracks in an aircraft Al-alloy after shot peening

Popis výsledku v původním jazyce

The paper contains results of an investigation of an effect of shot peening on initiation and growth of physically short fatigue cracks in an aircraft V-95 Al-alloy, which is of a similar type as 7075 alloy. The first part deals with an adaptation and verification of direct current potential drop (DCPD) method for detection and measurement of short crack initiation and growth in flat specimens of specific shape and dimensions. Physically short fatigue cracks of the length from 0.2 mm to more than 3 mm,most of them between 0.8 ? 1.5 mm, were prepared under high cycle fatigue loading. Specimens with existing short fatigue cracks were shot peened. Development of crack growth after shot peening was compared with crack growth in specimens without shot peening. Retardation of crack growth was significant particularly for cracks shorter than 2 mm.
