✦ Synopsis

Crack propagation tests were performed on 2024.T3 and 707%T6 specimens. Crack growth ~a\ ob\erved under variable amplitude loading. during high stress-amplitude cycle. associated with 4Ymode cr;lcking. whereas the crack front orientation was still at an angle of 90". Similarly it wa$ also studied during low, \tre\-amplitude c),clez ;tssociated with 9Wmode cracking. whereas the crack front was already at >I 45" ;Incle. Crack growth curve, fractographic information and a hrief dixussion on interaction effects during fatigue damage :Iccumulation are presented. K stress intensity factor kc kilocycle = I000 cycles I semi crack length, see Fig. 2 n number of cycles S., stress amplitude 1 S,,, mean stres\ j gross stress AS stress range NOTATION

A fatigue crack growth rate in consideration of fatigue damage accumulation and the mean stress on fatigue material elements ahead of a crack tip are derived using Both Miner's rule and the Manson-Coffin relationship. The theoretical equation of fatigue crack growth rate is shown in terms of J-integ
