Probabilistic Lifetime Predictions Using Total Stress Concept, Remote Monitoring and Global Wave Forecast Models: Fatigue Analysis of Damen’s FCS5009 Vessels

At Damen’s Research and Development department, continuous improvements are made to existing design practices using recent technological developments and fatigue design is currently on the anvil. High speed craft operating around the globe are subject to millions of load cycles (resulting from ocean waves) and therefore suffer from metal fatigue...

Fatigue of Welded Joints in Steel Marine Structures: Resistance of Double Sided Longitudinal Attachments and Single Sided Butt Joints ~ Design and Testing Considerations

Fatigue failure is a governing limit state for marine structures. Marine structures are composed of the numerous structural members connected by the welded joints which are the typically governing fatigue sensitive locations. In this thesis, attention has been paid to...

Fatigue Damage Sensor: Improving fatigue lifetime predictions of aluminium high speed craft

Monitoring fatigue damage is complex because ships are designed to crack after 20 years, and typically cracks will only occur after a long time. A novel fatigue damage sensor has been invented to indicate damage in corresponding aluminium welded joints. Fatigue damage is accelerated by introducing a stress concentration in the sensor w.r.t. the...
