The Effective Notch Stress Approach for a Tubular Joint

Offshore wind energy production is increasing rapidly and optimising the design of support structures has the potential to significantly reduce steel and costs. Jacket structures are commonly selected for deeper waters, and the design of these structures is primarily influenced by the fatigue performance of the tubular joints. The fatigue...

Impact of spatial variability of subsoil stiffness on immersed tunnels

Due to increased traffic density, there is a tendency to construct larger immersed tunnels with larger tunnel elements both in transversal and longitudinal direction resulting in a more critical design of the joints. Especially for those tunnels with relatively soft foundation and high siltation, there is no mature experience for reference. This...

Robust hand motion tracking through data fusion of 5dt data glove and nimble VR kinect camera measurements

Vision based interfaces for human computer interaction have gained increasing attention over the past decade. This study presents a data fusion approach of the Nimble VR vision based system, using the Kinect camera, with the contact based 5DT Data Glove. Data fusion was achieved through a Kalman filter. The Nimble VR and filter output were...

Explanation of the strength of nailed particle board-to-wood joints

By the earlier derived theory of the embedding strength, based on limit design, it is possible to explain the extremely high embedding strength of nailed particle board to wood joints leading to a new exact failure equation for the embedding strength as necessary correction for design and for the Codes.
