Description:: Recent advancements in processing and manufacturing techniques have spurred an exponential increase in use of polymer nanocomposites in a variety of applications. A key challenge in using these nanocomposites effectively is the dispersion of nanoparticles in the polymer matrix. Matrix-free assemblies of polymer grafted nanoparticles, called hairy nanoparticles assemblies(aHNPs) have...

Description:: The staggered (or imbricated) lamellar ``brick-and-mortar" nanostructure of nacre endows nacre with strength and fracture toughness values exceeding by an order of magnitude those of the constituents, and inspires the advent of new robust biomimetic materials. While many deterministic studies clarified these advantageous features in the mean sense, a closed-form...

Description:: Modeling the mechanical performance of metal produced with additive manufacturing (AM) has proven to be a challenging task. In the as-built state, these materials have been shown to exhibit strong heterogeneity and anisotropy. Even after post-processing, such as heat treatment or hot isostatic pressing and depending on the alloy, some...

Description:: Additive manufacturing (AM) processes have advanced rapidly over the last three decades to the point where they have the potential to fundamentally change the way complex parts will be designed and fabricated in the future. Additive methods leverage the ability to join metal particles or molten droplets in a layer-by-layer...

Description:: 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...
