Original abstract

Fatigue crack grows faster in the integral structure than in the riveted structure. This study compares the bonded, cold-sprayed and ultrasonically consolidated crack retarders to increase the fatigue life of integral airframe structure. The 2024-T351 aluminum M(T) specimen reinforced with crack retarders made of AISI 301 and 316L steels, Ti-6Al-4V titanium alloy and unidirectional CFRP laminate are evaluated in terms of fatigue life, delamination resistance and weight efficiency. Specimens were subjected to constant amplitude loading up to the final failure. A substantial decrease in fatigue crack growth rate was achieved using the ultrasonically consolidated AISI 301 crack retarder.
