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,

Basak

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 . 

DISCOVERY OF Oofelie V2.6,

an industrial multiphysics solution fully integrated in Samcef Field , the gui also used by all Samcef solutions.

About Open-Engineering and Oofelie®

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.

Xuanhe Zhao and Zhigang Suo  We develop a thermodynamic model of electrostriction for elastic dielectrics capable of large deformation. The model reproduces the classical equations of state for dielectrics at small deformation, but shows that some electrostrictive effects negligible at small deformation may become pronounced at large deformation.

These type of projects are interesting, when a mechanics-based one?

Hi

I am looking for a travelling long distance microscope for measurement of crack length. I will use this microscope on Instron fatigue test machine. I found some long distance microscopes on the web. But they are not appropriate for us. I attached a figure showing the travelling microscope that I would like to buy.

Do you have any suggestion about it? Where can I find it?

Thanks 

Dear All,

 Is there a source of free material data property files for use in ANSYS Simulation? I am looking for a file representing the properties of Neodymium Iron Boron (38) (permanent magnet material) to apply to a simulation of a motor. 

 Thanks for any help!

I have read a slide of Prof. Suo, he mentioned the large deformation in gels. Could you give some applications of this phenomenon in practice?

Graduate research assistantship is available immediately for a M.Sc or Ph.D student in micromechanics modeling of wood-based composites.  The study will be performed jointly at the University of British Columbia and FPInnovations – Forintek, in Vancouver, Canada.  Interested candidates with mechanics background are encouraged to apply via email: Chunping.Dai@fpinnovations.ca.  The application should include: a cover letter (stating research interest and qualifications), CV (listing of major courses taken and records), and three references.
