Dear Colleagues,
You are cordially invited to submit your one-page abstract to our Mini-Symposium (MS108) "Multiscale Modeling in Bio-Mechanical Systems" for
USACM's 14th U.S. National Congress on Computational Mechanics (USNCCM14)
Date & Location:
the Palais des Congrès de Montréal, Québec, Canada, July 17-20, 2017
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.
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.
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.
To appear in Journal of Elasticity
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.
It gives me great pleasure to announce the outcome of the 2016 competition for the Eshelby Mechanics Award for Young Faculty. This award is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. The selection committee consisted of: K. Ravi-chandar (UT Austin), Huajian Gao (Brown University), G.

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.
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.
A research group at Iowa State University (https://www.aere.iastate.edu/lmxiong/) is looking for research assistants in the field of solid mechanics, computational mechanics, computational materials science and engineering. Research topics will fall into a broad area of modeling and simulation of mechanical and transport behaviors, such as plasticity, fracture, phase transformation, thermal transport, or mass transport, in a variety of engineering materials.
