Flowing granular mixtures with species differing in some property, such as size, shape or density of the grains, tend to segregate (de-mix) during flow. Since flowing granular materials are common in industry, and since segregation is often unwanted and costly, understanding and mitigating segregation is an important concern in industrial...
The tension-spoke bicycle wheel owes its stiffness and strength to a cooperative relationship between the rim and the spokes: the rim holds the spokes in tension to prevent them from buckling under external loads, while the spokes channel external forces to the hub and prevent the rim from becoming severely...
Using carbon fiber reinforced plastics (CFRPs) to reduce vehicle weight has received growing attentions because it can effectively curtail greenhouse gas emissions and slow down global warming. The thermoforming process is among the most promising techniques for mass production of CFRP parts because it is highly automated and has relatively...
Additive manufacturing is a promising process that has the capability to build components with complex geometries for structural and biomedical applications. Due to the rapid and localized directional solidification of molten metallic alloys, unique phase transformations occur at the melt pool that can provide for components with greater strength and...
