The micromechanisms related to ductile failure during dynamic loading of single crystal Cu are investigated using large-scale molecular dynamics (MD) simulations. Void nucleation, growth, and coalescence is studied for a single-crystal Cu system unde

Large-scale molecular dynamics (MD) simulations are used to understand the yield behavior of nanocrystalline Ni and Cu with grain sizes ⩽10 nm at high strain rates. The calculated flow stress values at a strain rate of 109 s−1 suggest an asymmetr

A micro-scale computational tool, based upon an explicit digital element method (DEM), has been developed for numerical simulation of ballistic impact and penetration of textile fabrics. In this approach, each yarn is digitized as an assembly of digi

Large-scale molecular dynamics (MD) simulations are used to understand the macroscopic yield behavior of nanocrystalline Cu with an average grain size of 6 nm at high strain rates. The MD simulations at strain rates varying from 109 s−1 to 8 × 109

We present a simple “top-down/bottom-up” strategy to fabricate nano- and micropatterned polymer brush arrays composed of pH- and salt-sensitive, weak polyelectrolyte copolymers [poly(N-isopropylacrylamide-co-methacrylic acid, 3:1, poly(NIPAAM-co-

Stimulus-responsive macromolecules have attracted significant interest due to their potential applications in molecular motors, drug delivery, sensors, and actuation devices. Poly(N-isopropylacrylamide) (pNIPAAM) alone or as a copolymer is a stimulus

In this paper we report the surface-initiated polymerization of poly(N-isopropylacrylamide) (pNIPAAM), a stimulus-responsive polymer, from monolayers of ω-mercaptoundecyl bromoisobutyrate on gold-coated surfaces. pNIPAAM was polymerized in aqueous s

Stimulus-responsive, surface confined poly(N-isopropylacrylamide) (pNIPAAM) brush nanopatterns were prepared on gold-coated silicon substrates in a “grafting-from” approach that combines “nanoshaving”, a scanning probe lithography method, wit
