Program available for 1st IC Abrasive Processes

Submitted by Dean Eastbury on

The oral presentation program for the 1st International Conference on Abrasive Processes (ICAP-1) is now available at the conference website (www.icap.elsevier.com). Evolving from earlier meetings [the International Conference on Liquid and Solid Impact (ELSI-IX) and the International Conference on Erosive and Abrasive Wear (ICEAW-II)], ICAP-1 will be held in the historic city of Cambridge, England, 21-25 September 2008. You are invited to join your peers by registering for this popular single-stream meeting.

ResearcherID, a unique identifier of a researcher

Submitted by Zhigang Suo on

On the Web of Science my name appears sometimes as Suo Z and sometimes as Suo ZG.  If I search for Suo Z*, papers by a biologist named Suo ZM mix in.  Now Suo is a very rare name.  I cannot imagine how Wang JS searches for his papers.  Last year Michelle Oyen and I talked about assigning a unique identifier to each researcher, much like assigning an ISBN to each edition of a book, or assigning a DOI to each paper.

How simulate slurry's filtration in porous media?

Submitted by Xiangpeng Kong on

I wanna simulate the penetration of the slurry into soil when TBM is used to construct tunnel.  Although much more research has been done by experiments,I wanna use CFD to simulate the process which can make it more common and efficient.

For it is very similar to filtration cake physically,I would like to use some results by this.But it is very difficult to sumulate it by the software ANSYS CFD.

Is there some guy who have tried is field?Any suggestion will be appreciated!

IMMEDIATE PDFs VACANCIES IN WING MORPHING

Submitted by meguid on

Immediate vacancies exist for high calibre postgraduates and postdoctoral fellows who have interests in wing morphing and aerospace design, finite element modelling, aerodynamics, optimization, testing and validation. Candidates should expect excellent facilities, good salaries and exceptional working conditions.

Post-doc Vacancy for Molecular Dynamics studies of Polymer Adhesion

Submitted by Erik Van der Giessen on

The Micromechanics of Materials group in Groningen (the Netherlands) has an opening for a PostDoc to study the adhesion of polymers by meands of Molecular Dynamics simulations. The two-year position is part of a collaborative, multiscale modeling project in which other groups in the Netherlands focus on more macroscopic models. More info on http://micromechanics.phys.rug.nl/index.php?s=Openings or by contacting E.van.der.Giessen [at] rug.nl.

How to cut finite elment model from a geometry model?

Submitted by Yue Yang on

Hello all! I imported an .inp file model which was converted from another .am file into Abaqus. This model (model 1) doesn’t include any geometry information but only has 3D finite element model. I want to create an air model (Cube) surrounding model 1, subtracting model 1 from air model and leave a hole whose shape is the same as model 1. Then I want to insert model 1 to the hole again and compute acoustic problem. The question is: I can’t use ‘cut/merge’ function in Abaqus because there is no geometry information in model 1. Could someone tell me how to do that? Thanks very much.

Continuum interpretation of virial stress in molecular simulations

The equivalence of the virial stress and Cauchy stress is reviewed
using both theoretical arguments and numerical simulations. Using
thermoelasticity problems as examples, we numerically demonstrate that
virial stress is equivalent to the continuum Cauchy stress. Neglecting

How to do sound transmission in solid in Abaqus?

Submitted by Yue Yang on
Choose a channel featured in the header of iMechanica

Hello all. I am a phd student from UNB. Now I want to use Abaqus to simulate acoustic problem which is sound transmission from fluid such as air to solid. The outputs I want to get are acoustic pressure in fluid and solid, especially inside solid. What I did before is treating solid as fluid by using acoustic medium. However, the mechanics of solids are fundamentally different from fluids, and its not sensible to treat them the same. For example solids support shear, while fluids do not. Hope someone could answer my question. Thanks a lot.
