In this paper, a computationally efficient shallow water model is developed for sediment transport in the Yangtze Estuary by considering mixed cohesive and non-cohesive sediment transport. It is firstly shown that the model is capable of reproducing tida...

Effective control of the cohesive force between hydrate particles is the key to prevent their aggregation, which then causes pipeline blockage. The hydrophilic?lipophilic balance (HLB) value of surfactants was proposed as an important parameter for the e...

Injecting water into a coal seam to enhance the cohesive strength of coal and thus minimize and reduce the coal wall spalling risk must be considered in underground coal mining systems. In general, coal with low cohesive strength contains clay minerals w...

Rigid monopiles with small slenderness ratios (i.e., ratio of monopile embedded length to outer diameter) are widely used as foundations to resist lateral load and moment transferred from superstructures, e.g., large diameter steel pipes used by offshore...

The rehabilitation of steel structures with Fibre Reinforced Polymers (FRP?s) may appear less effective because they can be bolted or welded with steel plates that display the same mechanical properties. However, this technique has some unwanted conseque...

The interface crack of a slab track is a fracture of mixed-mode that experiences a complex loading?unloading?reloading process. A reasonable simulation of the interaction between the layers of slab tracks is the key to studying the interface crack. Howev...
