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 of Fatigue Damage Estimation in Transverse Frame of Ship Hull Structure using Pattern Load Method
Pattern Load FPSO Fatigue Damage
2009/5/12
The strength estimation of ship hull structures on the design-by-analysis including wave load, structural response and stochastic fatigue analysis is increasing in number recently due to the advance o...
On the Damage of the Acoustic Window at the Bottom of an Ocean Observation Ship
ADCP Breaking Acoustic Window Water Pressure Slamming Short Term Prediction
2009/5/12
The circular plastic window (we call it as acoustic window) at the bottom of a large ocean observation ship was broken sometimes. This window is a cover of the downward hole of the recess of the ADCP ...
Cyclic stress-strain relation under high cycle fatigue process-Elastoplastic constitutive model incorporating cyclic damage-
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...
Wide-range and Short-term Damage Detection of a Large Floating Structure
Wide-range Short-term
2009/3/27
Realization of a large floating structure is considered to be effective for ocean space utilization in Japan. As examples of ocean space utilization, floating airport, container terminal and offshore ...
