i have an optimization program for structural problem in Matlab software. i found design variables from  Matlab. i want to interface this program in to ansys softare to find optimum stress and strain. how can i interface matlab program in to ansys. if any sample tutorilas please send me. 

Making the Right Moves: A Practical Guide to Scientific
Management for Postdocs and New Faculty

Based on courses held in 2002 and 2005 by the Burroughs Wellcome Fund and
HHMI, this book is a collection of practical advice and experiences from
seasoned biomedical investigators. The second edition contains three new
chapters on laboratory leadership, project management, and teaching and course
design.

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.

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

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

"

Refutation of Cauchy stress

The theory of stress based on Euler & Cauchy is now refuted. The profound incompatibility of this theory with the rest of physics, especially the theory of potentials and the theory of thermodynamics, has been documented in

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.

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.

hallo, everyone...all of the ANSYS user out there, plx help me..currently i am the final semester student of bachelor mechanical engineering.My final year project is Piezoelectric sensor  using ANSYS for simulation. I facing problems now..i dont knw how to use ansys to perform the simulation. plx provide me a step by step tutorial.i tried b4 and the simulation fail due to the meshing problem. The Piezoelectric sensor simulation is exactly same like the tutorial provide by ansys in the HELP topic.>>( Piezoelectric Bimorph beam)..If u guys had done it or tried the simulation b4..plx send the file to my email . thanks you very much..i am working partime to finance my living expenses..i am very exhausted..plx help me ..thanks.

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.

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.

At this moment, we have an excellent keynote line-up, including the following individuals: Prof. Ahmed Noor (Old Dominion University), Dr. Takeshi Abe (Ford Motor Company), Prof. Tom Hughes (Univ. of Texas-Austin), Prof. Mary Boyce (M.I.T.), and Dr. Joel Orr (Cyon Research).

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

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)

could you please give me a reference about multiscale fluid mechanics?

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.

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

Recently, a new carnival called The Giant's Shoulders has been started and the first edition of the same is out at A blog around the clock. A post of mine on the elastic stresses due to inclusions and inhomogeneities made it to the carnival. I am cross-posting the piece here since it might also be of interest to the readers of iMechanica (though I did post a short note earlier here which forms the core of this long post too).

Using Computational Biology to Bring Predatory Dinosaurs Back to Life

The proposed programme of research seeks to use state-of-the-art computational techniques to reverse engineer the walking cycle of a predatory dinosaur. Software for image-based modelling, parallel finite element analysis and evolutionary robotics will be coupled and deployed
over a computational Grid comprising many thousands of processors. This resource will facilitate a range of unique meta-experiments, enabling new scientific research to be undertaken that would otherwise not be possible. Not only will these experiments provide insight into the evolution of

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.

UPDATE:  IT APPEARS THAT HARZING HAS TWO PAPERS ON THIS IDEA, SEE ATTACHED.

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.

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:

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,
