Structural loading of cross deck connections for trimaran vessels
… the fundamental relationships of wave loading on cross deck structures for trimaran vessels. In contrast with a monohull ship, trimaran vessels experience several possible structural loading cases including: longitudinal bending, transverse bending, torsional bending, spreading and …

Scale Modeling of Tests with Combined Thermo-Structural Loading
… article while maintaining the same thermal and structural response exhibited in the large-scale test. The developed scaling methodology incorporates uniform geometric scaling, Fourier number time scaling, and furnace boundary condition matching. The scaling laws were experimentally validated …

Implementing Impedance - Based Health Monitoring
… wire length and ambient conditions (temperature, structural loading and vibration). It was concluded that increasing the applied voltage improves the signal to noise ratio and damage detection abilities. Test wire lengths under 30m do not affect damage detection abilities. The technique is able to …

Bench Scale Characterization of Joints and Coatings
… fire resistance, including heat transmission and structural integrity. The test requires specialized furnaces and full-scale assemblies that are 3.0 m (10 ft) or more on each side, making it very expensive to perform. In this study, we investigated the feasibility of the scaling methodology for a …

The effect of dynamic operation and incoming flow on the wake of a utility-scale wind turbine
… lead to power losses up to 40% and increased structural loading on downwind turbines within a wind farm. To mitigate these detrimental effects, improved understanding of wake behavior is required. However, modeling wind turbine flows in the laboratory or in simulations is hindered by the wide …

Characterising the Mechanical Loads Acting on Nuclear Packages during Rail Transportation
… a more thorough understanding of the mechanical loading acting on heavy nuclear packages during rail transportation. There were two motivating factors for this study. Firstly, the design of equipment used to tie down a package to its conveyance has become more challenging with the recent trend of …

A method for identifying structural load share opportunities in aircraft powerplant configurations
… higher levels of thrust. Consequentially structural and thermal demands will increase on individual power plant components. Under current design practice the various sub-systems (for example: nacelle, inlet, thrust reverser, engine core casings and the pylon mounts) are designed …

Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
… The three-dimensional flow development and structural loading on the finned cylinders are studied using Large Eddy Simulation. In addition to the flow entrainment mechanism in between the fins, another entrainment mechanism in the near wake is found to be caused by the downwash flow induced …
