Postdoctoral position in multiphysics and nanoscale mechanics modeling

A postdoctoral research position is available immediately in the Johnson research group at the University of Illinois at Urbana-Champaign.  The position will involve continuum finite element modeling of multiphysics and interfacial phenomena in micro- and nanoscale electronic materials processing applications.

Xu and Needleman: Potential function in 3-D

Dear all,

I am improving the cohesive zone model in 2-D proposed by Y.F. Gao to simulate delamination between sub-micron thick films in 3-D. However, I did not find the potential function proposed by Xu and Needleman in 3-D. If you know it please tell me

A new theory of stress?

I was browsing the discussion page for Stress in Wikipedia when I came upon this interesting comment:

Refutation of Cauchy stress

Ph.D position at EPFL-LSMS, Switzerland

Graduate assistantship positions are available in the Computational olid Mechanics Laboratory (http://lsms.epfl.ch/) at the Ecole olytechnique Fédérale de Lausanne (http://www.epfl.ch/).
We are interested in highly motivated Ph.D. candidates with an academic background (B.S. and M.S.) in either Mechanical Engineering, Civil ngineering or Computational Materials Science.

Mechanics-based nanotribology

Surface and Grain boundary

Surface:

If it's a free surface, the dislocation can penetrate through the surface easily, but, if it's a coating or oxide layer, it will be hard for dislocation to glid out of the surface

Grain boundary:

In discrete dislocation dynamic simulation, some authors take grain boundary as a impenetrable, such as a rigide wall, But in other papers, grain boundary was thought to be a penetrable wall.

 So,Is there somthing or simillar property for us to derive.

ANSYS 11.0

franc3d and ansys

I am studying crack simulations.I am familar with ansys,and i know franc3d files could output into ansys files ,but i don't know how. I just get .fem files from franc3d. But how could .fem files be read into ansys?  Could anyone give me some details?  I'll be very grateful.

NAFEMS NA 2008 Regional Summit: NAFEMS 2020 Vision of Engineering Analysis and Simulation (Hampton, VA - Oct. 29-31, 2008)

Hi everyone,

I just wanted to let everyone know about the upcoming NAFEMS North American 2008 Regional Summit: NAFEMS 2020 Vision of Engineering Analysis and Simulation. This is an excellent opportunity for academic researchers, industrial practitioners and software developers to meet for mutual benefit.

For those of who you not familiar with NAFEMS, it is a non-profit, vendor neutral, engineering analyis community.

Free video lecture collection!

Hi ,everyone I find this page very useful ,it has many free mechanical luctures,maybe you well find something useful like me .Please enjoy!

ANSYS - Loads on deformed shape

This might be a stupid question but, is it possible to apply loads on a deformed shape in ANSYS? (after applying a set of loads, getting the deformed shape  and applying another set of loads on the deformed shape)

The full list of journals ranked by H index --- but not the list of highlycited papers :(

After some conversation with Roozbeh which are "irritatingly useful" :) I found that this site has done already all the calculations we need http://www.scimagojr.com/  except the list of highlycited papers which remains for me the most interesting aspect and which we seem to need to do manually as we did yesterday with IJSS and JMPS at Most cited papers and H-factor of some mechanics journals -- IJSS

Some results are attached as a big PDF file.

3rd Int. Conference on Integrity, Reliability and Failure, Porto, Portugal

Dear Colleague:

We are pleased to bring to your attention the First Announcement & Call for Abstracts for the

3rd International Conference on Integrity, Reliability & Failure

to be held in Porto, Portugal

July 20- 24, 2009.

IMPORTANT UPDATE JULY 18

The full list of journals ranked by H index

It is possible to rank journals equally as authors, using e.g. the Harzing Publish or Perish sofware based on Google Scholar. I did the excercise for IJSS. It turns out the H-index is 78 (slightly higher than even the best authors in solid mechanics, but not stellar).  In the most highlycited papers, we find good names, but not stellar papers.

The results may be affected by the limitations of the software.

Mesoscopic model for mechanical characterization of protein materials

We consider the mesoscopic model of protein materials composed of protein crystals with given space group for understanding the mechanical properties of protein materials with respect to their structures. This preprint was accepted for publication at Journal of Computational Chemistry.

Entropy production on a single trajectory of the small system

The following PowerPoint file is from the talk which I gave in my research group recently. It is also my understanding and reading notes from a serial of papers by Prof. Udo Seifert, in which he generalized the entropy production on a single trajectory of the small system such as a molecular machine. It mainly addresses three questions:

3D modeling of composite material in ANSYS

Hi,

I am trying to model a composite material in ANSYS. I have used ANSYS for simple simulations before but I have never done composite material analysis. I have attached a simple schematic of what I am trying to model. Can you guys please help me? Any tip you can give will help. I have limited time. 

Thank you,

Basak

 

Viscoelasticity in Abaqus

Hi All,

 I would like to use Abaqus to model the viscoelastic material  behaviour of a polymer.


I have material data from a simple uniaxial creep experiment (nominal strain vs time).  I tried to use the viscoelastic material model in Abaqus.  I am a bit confused as to how I need to enter my data (what format). 

The manual says I have to specify the normalized bulk and normalized shear compliance

Puzzle: What caused this failure?

Here's a puzzle for our readers.  The following image is of the surface of a failed joint followed by a picture of the joint (not the same one but a similar one) before joining.  What material is it? What caused the failure?  All manner of speculation is welcome.
