✦ Synopsis
The characteristics of fatigue crack propagation behavior near the thickness interface were eiamined for 6061 T6 aluminium specimens. A series of thin to thick type various thickness specimens was prepared. Fatigue tests were performed under load control in tension-tension. Correction factor of the stress intensity factors (SW) for various thickness specimens was introduced as the form of Ffa, 0) where a was a dimensionless crack length and p was the thickness ratio. These correction factors were determined experimentally by means of linear elastic fracture mechanics concepts.
