Suppression of Shear Banding and Transition to Necking and Homogeneous Flow in Nanoglass Nanopillars

In order to improve the properties of metallic glasses (MG) a new type of MG structure, composed of nanoscale grains, referred to as nanoglass (NG), has been recently proposed. Here, we use large-scale molecular dynamics (MD) simulations of tensile loading to investigate the deformation and failure mechanisms of Cu64Zr36 NG nanopillars with large, experimentally accessible, 50 nm diameter.

Hydraulic Fracture and Toughening of a Brittle Layer Bonded to a Hydrogel

AbstractBrittle materials propagate opening cracks under tension. When stress increases beyond a critical magnitude, then quasistatic crack propagation becomes unstable. In the presence of several precracks, a brittle material always propagates only the weakest crack, leading to catastrophic failure. Here, we show that all these features of brittle fracture are fundamentally modified when the material susceptible to cracking is bonded to a hydrogel, a common situation in biological tissues.

A zinc oxide/polyurethane-based generator composite as a self-powered sensor for traffic flow monitoring

A zinc oxide (ZnO)/polyurethane (PU)-based generator composite was fabricated and its piezoelectric performances were examined in the present work. In addition, the influence of multi-wall carbon nanotubes (MWNTs) and copper powder incorporation on the piezoelectric performance of composites was also studied. The performance level of the composites with various ratios of the constituents was compared in terms of piezoelectric responses obtained from three different tests, i.e., foot stamping, vehicle loading, and cyclic wheel loading tests.

PhD Openings in ME and MSE at SUNY Binghamton

1. Research Assistantship (RA) for a PhD Student in Mechanical Engineering An NSF-funded research assistant position is available for a new PhD student in Mechanical Engineering at the State University of New York (SUNY) at Binghamton. The research is focused on materials printing using a hybrid inkjet-electrospray technique. The goal is to print highly-ordered monolayers of functional nanoparticle inks at high throughput. The student?s research will be experimental; however, close collaboration is expected with faculty and students in materials science and computational physics.

A multi-scale modeling framework for instabilities of film/substrate systems

Spatial pattern formation in stiff thin films on soft substrates is investigated from a multi-scale point of view based on a technique of slowly varying Fourier coefficients. A general macroscopic modeling framework is developed and then a simplified macroscopic model is derived. The model incorporates Asymptotic Numerical Method (ANM) as a robust path-following technique to trace the post-buckling evolution path and to predict secondary bifurcations.
