Abstract
A technique is proposed for estimating crack opening stress during fatigue crack growth. It involves electron fractography of fracture surfaces obtained under specially designed load sequences. The technique was experimentally validated on an Al---Cu alloy. The experimental data bear evidence of fatigue crack closure. They also indicate that fatigue crack closure is uneven across the specimen thickness.
