Short fatigue crack growth in an aircraft Al-alloy of a 7075 type after shot peening
Original language description
An effect of shot peening with two groups of parameters representing limits for practical use in service on growth of physically short fatigue cracks in a 2.4. mm thick sheet of an aircraft V-95 Al-alloy (a type of a 7075 alloy), clad with a 7072 Al-alloy (Al-Zn1) was investigated. Using the improved experimental methodology, physically short fatigue cracks of the length from 0.2. mm to more than 3. mm, most of them between 0.8 and 1.5. mm, were prepared under high cycle fatigue repeated tensile loadingof the constant nominal stress range 160. MPa, load asymmetry R. =. 0. Specimens with existing short fatigue cracks together with some specimens with no cracks were then shot peened using two different groups of parameters. Microhardness measurement andinformative measurement of residual stresses near the peened edges were carried out. Development of crack growth after shot peening were measured and compared with crack growth in specimens without shot peening. Retardation of crack grow
