Postdoctoral position on multiscale modeling of microstructural development

IMDEA Materials Institute is looking for a post-doctoral researcher
(PhD in Materials Engineering, Metallurgy, Mechanical Engineering, Computational Materials Science) (Ref: PD02-VIR) to work in the research project VIRMETAL (virtual design, virtual processing and virtual testing of metallic materials) funded by an Advanced Grant of the European Research Council. Research activities will be focused in the development of multiscale modeling strategies –based on the phase-field method– to simulate the microstructural development during solidification as well as during thermo-mechanical treatments in Al and Mg alloys.

What's That Stuff

A few years ago I bought a Chinese book titled 你身边的化学.  The book contains articles about chemistry in everyday life.  The authors collected these articles from magazines and websites, and translated them into Chinese.  In particular, the authors mentioned a column, called “What’s That Stuff”, in Chemical & Engineering News.

moving singularities (crack analogues) in fretting fatigue

    The stress concentration induced by fretting fatigue was studied with a simple "Crack Analogue" model (CA) by the MIT group of Suresh in the late 1990's, which was then "improved" by the present author to take into account simply both contact loads and bulk stresses loads, and even the case of finite stress concentration in the so-called "Crack Like Notch Analogue" (CLNA) model.

Fracture and singularities of the mass-density gradient field

A continuum mechanical theory of fracture without singular fields is proposed. The primary
contribution is the rationalization of the structure of a `law of motion' for crack-tips, essentially
as a kinematical consequence and involving topological characteristics. Questions of compatibility
arising from the kinematics of the model are explored. The thermodynamic driving force
for crack-tip motion in solids of arbitrary constitution is a natural consequence of the model.
The governing equations represent a new class of pattern-forming equations.

Effects of SiC, SiO2and CNTs nanoadditives on the properties of porous alumina-zirconia ceramics produced by a hybrid freeze casting-space holder method

Highly porous alumina-zirconia ceramics were produced by adding space-holder materials during freeze casting. To increase the strength of porous ceramics, different amounts of nanoadditives (silicon carbide-SiC, silica-SiO2, and multi-wall carbon nanotubes-CNTs) were added. Space-holder materials were removed by preheating, and solid samples were produced by sintering. Up to 68% porosity was achieved when 40% space-holder was added to the solid load of slurry. Wall thicknesses between pores were more uniform and thinner when nanoadditives were added.

Rational design of reconfigurable prismatic architected materials

Advances in fabrication technologies are enabling the production of architected materials with unprecedented properties. Most such materials are characterized by a fixed geometry, but in the design of some materials it is possible to incorporate internal mechanisms capable of reconfiguring their spatial architecture, and in this way to enable tunable functionality.

Molecular dynamics simulations of mechanical behavior in nanoscale ceramic –metallic multilayer composites

The mechanical behavior of nanoscale ceramic–metallic (NbC/Nb) multilayer composites with different thickness ratios is investigated using molecular dynamics (MD) simulations. Based on the obtained stress–strain behavior and its dependence on temperature, strain rate, and loading path,the flow stress for the onset of plasticity is identified and modeled based on the nucleation theory,and the in-plane yield loci for different layer thicknesses are constructed. The results are used to establish the plastic flow potential for developing a continuum viscoplastic constitutive model for

A perspective on the statistical mechanics of 2D materials

2D materials are fascinating for numerous reasons. Their geometrical and mechanical characteristics along with other associated physical properties have opened up fascinating new application avenues ranging from electronics, energy harvesting, biological systems among others. Due to the 2D nature of these materials, they are known for their unusual flexibility and the ability to sustain large curvature deformations. Further, they undergo noticeable thermal fluctuations at room temperature.
