How to input LaTeX equations in iMechanica

 

Last time, when I saw one blog of , I thought it would be much more convenient if we can input some equations in iMechanica for discussion. When I make discussion about mechanics with colleagues, I would like to write down some equations on the blackboard or paper. For discussion based on the web blog, LaTeX equations will be helpful. And it would be better if one can input equations directly instead of uploading one picture after another.

FailureCriteria.com

     A new website http://www.failurecriteria.com has been initiated which surveys mechanics type failure criteria for homogeneous materials.  Although later additions will be concerned with anisotropic materials, the first topic of attention is that of yield and failure criteria for isotropic materials.  A brief review of  the Mises, Tresca, and Coulomb-Mohr criteria is given, along with the need for a more general form which spans the various  materials classes i

FE optimization help

Hey guys (and gals). I have been working on a FEA. The problem I have been having is that I cannot find a FE package that allows for optimization to be performed. What I am trying to do is create a FE geometry parametrically and have the software change the specified parameters accordingly. I am currently trying Abaqus and I am unsure of how to assemble multiple objects into one geometry (say an extruded rectangle and cylinder). I am very new to using abaqus so I'm not sure what all it can do. I'm more familar with Comsol and Ansys. Thanks for any help.

Positions: Post doctoral and doctoral

Ph.D and post-doctoral positions available immediately in Professor Zikry's rsearch group at North Carolina State University, Raleigh, NC.

Currently, we have openings with researchers with backgrounds in computational solid mechanics, atomistic and molecular modeling, multiscale techniques, and fracture mechanics. We also have openings in experimental mechanics.

I can be contacted at zikry@ncsu.edu. Please forward latest cv.

Thanks

In preparing cases for faculty appointments, my colleagues in other fields often ask about citations of each candidate and his or her comparees.  Despite obvious resistance, my colleagues give following reasons:

Everything is miscellaneous (Video)

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!

 

How to deal with the constitutive integration in plasticity?

Plastic theory has been developed systematically. As a beginner, however, some questions have confused me for a long time.

As is well known, the constitutive integration must be deal with in the flow theory. Instead of the explicit algorithm such as M-iteration, the implicit one - stress update algorithm - has been attractive for its simplicity, the most famous of which is rp (return mapping) for J2 flow theory.

However, compared with M-iteration, it seems to be difficult to use the stress update algorithm for a complicate yield condition. Is it right?

Graduate Student or Graduate Employee?

Lately I have been thinking that "Graduate Student" is a misnomer. The correct title should be "Graduate Research Assistant" or "Graduate Engineer".  After more than a year spent in industry, I think that there really is no difference in the work done. Except that the work environment is more flexible in academia.

Kindle - The Future of Ink, part 2

A year ago in my first post, The Future of Ink, I explored e-ink technology and the e-book concept when the potential was still largely unseen. But since then, the industry has completely transformed, and the prospect of the e-book is beginning to be realized.

Science, as some see it...

I came across some content I used to have on my webpage a long time ago.

http://www.ce.cmu.edu/~amita/webpage_misc.html

Hopefully it is inspirational for that bright, young, graduate student waiting in the wings to usher in the revolution that shows us how to solve some of the outstanding theoretical problems of solid mechanics that we seem to put off  e.g. concrete, quantitative methods for calculating time-dependent microstructure in plasticity and its effect on time-dependent macroscopic properties.....

stable elements for mixed elasticity

I'm very interested in the choice of the finite element spaces for elasticity. I want to choose elements for the stress and the velocity, I was suggested to use piecewise constant for the stress and piecewise linear for the velocities to satisfy the Babuska-Brezzi condition. Is that right? I've heard that I can't use only 6 components for the stress in this way, but I must add some additional constraint to enforce its simmetry. I'm looking for additional documentation, but I can't find any. Has someone got any suggestion? Thanks.
