Abstract
Abstract In this study, the effect of cold expansion process on the fatigue behavior of hybrid (bonded-bolted) double shear lap joints has been investigated, numerically and experimentally. Also the effects of cold expansion process and adhesive bonding process on the fatigue behavior of simple bolted double shear lap joint are studied, separately. For this purpose, six batches of specimens were made from 7075-T6 aluminum alloy sheet in Simple and Hybrid groups. Simple group consists of simple, 1.5% cold expanded and 4.7% cold expanded batches. Hybrid group consists of hybrid, 1.5% cold expanded hybrid and 4.7% cold expanded hybrid batches. All of the specimens after assembling were put under cyclic loading. The S-N curves of the experimental results show that the cold expansion process increases the fatigue lives of Hybrid and Simple group specimens. This increase is more appreciable by increasing the cold expansion percent. The adhesive bonding of Simple group specimens increases the fatigue life of these specimens. For all specimens the fatigue life enhancement is more appreciable at the lower loads. Also, the rate of crack growth in Hybrid group is slower than that of Simple group.
