This paper presents a geometric discretization of elasticity when
the ambient space is Euclidean. This theory is built on ideas from
algebraic topology, exterior calculus and the recent developments
of discrete exterior calculus. We first review some geometric
ideas in continuum mechanics and show how constitutive equations
of linearized elasticity, similar to those of electromagnetism,
can be written in terms of a material Hodge star operator. In the
discrete theory presented in this paper, instead of referring to

Hi All :

I was wondering why some people prefer to use Non Local Model while some others use Implicit Gradient Model (which can be derived from Non Local Model) .

When implicit Gradient Model is itself derived from Non Local Model ,and its FE implimentation just involves an additional average to be calculated and what is the need to introduce gradient terms ??

Thanks Alot

A three-year
PhD studentship is available within the Glasgow Research Partnership in
Engineering (GRPE) as part of the Joint Research Institute in Mechanics of
Materials, Structures and Bioengineering at the University of Glasgow. 
The
specific goals of the PhD will be to manufacture MREs and determine the
influence of manufacture conditions on the micro-structure and magnetic-sensitivity
of the magnetorheological elastomers (smart material).

I am working on a project for a more efficient process for cleaning supe plastic forming dies. Currently, we are cleaning them manually with an electric drill motor and a brush on the end of that. This process is ergonomically doing a number on our employees, not say that the process is lengthy. Is there anyone that has had any luck with any other process cleaning dies? Thanks.....

In today's class of complex analysis, my co-instructor Scott Norris was lecturing on resonance.  He mentioned a YouTube video of the Tacoma Narrows Bridge.  Also instructive is the entry of the bridge on Wikipedia. 

I am in the process of applying for a PhD in computational solid mechanics in the US and I am about to take the GRE. Well I have been kind of busy at my work and didn't really get time to study the word list.

My question is, how much weight does the verbal part have in admission/fellowship/assistantship decisions? If I have really good GPA's and research experience with enthusiastic refrees, can I still make it with medicore results on the verbal part?

Dear Mechanics Colleagues,

H. Mei, Y. Pang, and R. Huang, International Journal of Fracture 148, 331-342 (2007).

Following a previous effort published in MRS Proceedings, we wrote a journal article of the same title, with more numerical results. While the main conclusions stay the same, a few subtle points are noted in this paper.

Full support is available for 2 PhD students in cellular mechanics group in Biomedical Engineering Department at Rensselaer Polytechnic Institute.  

The applicants should have mechanics, materials or soft matter physics background, with some experimental experience at micro-scales.  Experience with any of the following is considered a
plus: computational mechanics, cell/tissue culture, microscopy, image analysis, photonics.

The Chronicle of Higher Education just published its ranking of all programs (fields) of universities in the States.

http://chronicle.com/stats/productivity

This ranking is based on the productivity (publications, citations, grants and awards, nothing else), rather than people perceptions (department head's evaluations) as US News and World Report. 

Of course one should never take any ranking very seriously, but it is interesting to take a look at this website.

Two four-year doctoral fellowships at the LaCàN Research group (http://www-lacan.upc.es/), Universitat Politècnica de Catalunya (UPC, Barcelona, Spain).

These two fellowships, funded by the Spanish Ministry of Science and Education ("beca FPI"), coverfull tuition, a monthly stipend and provide funds for short international research stays. The starting date is expected in the Summer-Fall 2008.

2015 Themes and Discussion Leaders

In a previous post, Learning to be a PhD advisor, I wrote about learning to do my job from students.  Over the years, I have also learned from writings of other scientists on doing research, its dynamics:  competition, despair, and exhilaration...  Here is a small sample that occurs to me this morning. 

POSITION: 

The Department of Engineering Mechanics, University of Nebraska-Lincoln, invites applications for a tenure-track position at the Assistant Professor level for candidates with research experience or strong interest in cell/tissue biomechanics (mammalian or plant), nanodevices, bioMEMS/NEMS, nanomechanics/materials/manufacturing/fluidics, biomaterials, and biona­nomechanics. Exceptional candidates could be consid­ered for a higher rank. 

QUALIFICATIONS: 

The American Academy of Mechanics is pleased to announce that
Jacob Fish, the Rosalind and John J. Redfern Chaired Professor of Engineering at
Rensselaer Polytechnic Institute, and Martin Ostoja-Starzewski, Professor of
Mechanical Science & Engineering at University of Illinois have both been
elected as Fellows of the Academy. They will be presented with certificates
