A Continuum Model for Dislocation Pile-up Problems (Accepted by Acta Materialia)

Submitted by Xiaohan Zhang on

 

A continuum dislocation pile-up model is developed to solve problems with arrays of edge dislocations on one or multiple slip planes. The model solves pile-up problems in a discrete dislocation dynamics manner.  The effect of anisotropy and stacking fault energy can be naturally modeled. The model is validated by reproducing the solutions of problems for which analytical solutions are available. More complicated phenomena such as interlacing and randomly distributed dislocations are also simulated.

Master Mechanics of Materials and Structures for Civil Engineering and Transportation Systems, University Paris-East, France

Submitted by Julien Yvonnet on

The master Mechanics of Materials and Structures for Civil Engineering and Transportation Systems (MMSCT) is a one-year program offered at UPEM (University Paris-East Marne-la-Vallée), France (20 min from Paris center by transportations). The program aims at providing the students with deep scientific and technical knowledge about the multiscale modelling, over a broad range of scales, of complex materials and structures.

Postdoctoral position on multiscale modeling of microstructural development

Submitted by Javier LLorca on

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

Submitted by Zhigang Suo on

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

Submitted by Mike Ciavarella on

    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

Submitted by Amit Acharya on

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.

Yong Zhu is the recipient of the 2016 Eshelby Mechanics Award for Young Faculty

Submitted by Pradeep Sharma on

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.
