A Probabilistic Model Updating Algorithm For Fatigue Damage Detection In Aluminium Hull Structures
Probabilistic Model Updating Algorithm Fatigue Damage Detection Aluminium Hull Structures
2015/6/30
The use of aluminum alloys in the design of naval structures offers the benefit of light-weight ships that can travel at high-speed. However, the use of aluminum poses a number of challenges for the n...
A Study on Fatigue Strength Assessment of Welded Structures with Cruciform Joints
Cruciform Joints Weld Joint Ship Structure Fatigue SN Curve Hot Spot Stress Finite Element Analysis
2009/5/19
A large number of cruciform joints can be found in ship structures, but it is generally known that it is not clear how FEM stress output ought to be used and how FEM input ought to be prepared for fat...
Study on Evaluation of Fatigue Strength Based on Modified Miner’s Rule
Wave-Induced Load Fatigue Damage Modified Miner’s Rule Correlation Coefficient Reliability Analysis
2009/5/12
In case of evaluating fatigue strength the fatigue damage based on modified Miner’s rule is often used. This fatigue damage is simply calculated if the distribution of stress response is assumed to ob...

Cyclic stress-strain cycle fatigue process-Elastoplastic constitutive model cyclic damage
2009/4/24
In order to simulate mechanical fatigue phenomena represented by cyclic plasticity such as ratcheting and hysterisis loop, the plastic stretching within a yield surface has to be described, whilst the...
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...
