The cluster expansion formalism for alloys is used to investigate phenomena in several refractory alloys: Co3W (superalloy), NbTiVZr, HfNbTaTiZr, and AlHfNbTaTiZr (high entropy alloys). Density …
The discrete dislocation (DD) plasticity is truly mechanism-based plasticity and well-suited for mesoscale modeling in metal. The effects of size-dependent plasticity and plastic dissipation emerge …
Despite being composed of weak and brittle constituents, some structural biological materials, such as shell and bone, have relatively high strength and toughness. These materials …
The past decades have witnessed an increasing demand for characterizing mechanical properties of materials at small scales due to the miniaturization of devices. While tremendous …
Abstract of “Investigations on mechanical property - microstructure correlations in CMC Coatings” by Sugeetha Vasudevan, Ph.D., Brown University, May 2016 Carbon nanotubes (CNTs) are being …
Both interfaces and spatial gradients in engineering structures exhibit distinct mechanical properties in contrast to their bulk counterparts. The demands of both the aerospace and …
Surface plasmons are coherent oscillations of conduction electrons at dielectric/metal interfaces that can be excited, for example, by light scattering at sub-wavelength nanoscatterers. As one …
