Fatigue reliability of a stiffened panel subjected to correlated crack growth
Fatigue reliability Stiffened panel Crack growth Inspection Reliability updating
2012/4/26
The objective of this work is to analyze the fatigue reliability of a stiffened panel subjected to the growth of correlated cracks. A probabilistic crack growth model is applied, allowing for the exis...
Fatigue Crack Growth Behaviour of 6013 Aluminium Alloy at Different Ageing Conditions in Two Orientations
Fatigue Crack growth rate Aluminium alloy Ageing AA6013
2009/10/9
The effect of different ageing treatments on the fatigue crack growth behaviour of AA6013 aluminium alloy was investigated. C(T) (Compact Tension) specimens prepared in L-T and T-L orientations were a...
The asymptotic field of mode I quasi-static crack growth on the interface between a rigid and a pressure-sensitive material
pressure-sensitive material mode I quasi-static interface crack crack-tip field asymptotic analysis
2011/9/13
A mechanical model of the quasi-static interface of a mode I crack between a rigid and a pressure-sensitive viscoelastic material was established to investigate the mechanical characteristic of ship-b...
Improvement on the Fatigue Life of Welded Joints by the Synergy Effect of Ultrasonic Impact Treatment and Steel with High Resistance to Fatigue Crack Growth
Fatigue Life Welded Joints Ultrasonic Impact Treatment High Resistance Fatigue Crack Growth
2009/4/16
The extension of the fatigue life of welded joints has been in demand to improve the safety and reduce the life cycle cost of ships.To meet such demand, it is effective to apply post-weld treatments w...
Fatigue crack growth rates of rotor steel at elevated temperatures
rotor steels (30CrlMolV) fatigue crack propagation rate temperature
2011/9/14
Low fatigue samples were obtained from the outer edges of rotor steel (30CrlMolV) which had operated under different temperatures conditions.Based on this data,the effects of temperature on fatigue cr...
