Experimental investigations of welding induced temperature gradients and distortions in a segment of an OSD

Orthotropic bridge decks are susceptible to fatigue cracks which are influenced by the thickness of their components, welding procedure, type of the weld, the position of the considered detail in relation to the local loading condition and by residual stresses due to welding. The above-mentioned parameters determine the detail category for...

The effects of peening and hole expansion on the fatigue behaviour of 7079-T652 aluminium alloy

The effects of shot and glass bead peening and hole expansion on the direct stress fatigue life of 7079-1'652 aliiminium alloy specimens are considered. Three types of specimens were employed: unnotched, notched by a central hole and notched at comers. Shot peening was only slightly beneficial for high cycle fatigue, and then only for comer...
