The laser shock peening (LSP) process using a Q-switched pulsed laser beam for surface modification has been reviewed. The development of the LSP technique and its numerous advantages over the conventional shot peening (SP) such as better surface finish, higher depths of residual stress and uniform distribution of intensity were discussed. Similar comparison with ultrasonic impact peening (UIP)...

Fatigue and corrosion are the main reasons for failure of stay cables. Traffic load also plays a significant role in cable fatigue. To study fatigue life cables under combined action traffic corrosion, this originally deduced probability model steel wires, considering stress range average based on nonlinear damage model. Then, weight loss rate was introduced into wires order to obtain corroded ...

First row rotating blades of four axial-flow compressors were prematurely fractured. Previous investigations showed that the site atmosphere contains corrosive compounds which lead to an increase in possibility of pitting on the blades. It was also revealed that the crack was originated from two corrosion pits. Thus, this work is conducted to ascertain which of fatigue or stress corrosion crack...

Abstract Based on the three-stage fatigue crack growth model, a corrosion life prediction method considering coupling effect of and is proposed in this paper. In case, stress factor amplitude was claimed fatigue. Three push-out tests conditions were conducted to study failure mode studs. The propagation studs, obtained through tests, simulated FRANC 3D establish library adequate amplitude. Acco...
