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.

About AAM 

From Northwestern Engineering:

In a paper published July 26 in the journal Nature, researchers led by Rod Ruoff, John Evans Professor of Nanoengineering in the Robert R. McCormick School of Engineering and Applied Science, report on the development of "graphene oxide paper."

As a member society of the U.S. National Committee on Theoretical and Applied Mechanics (USNC/TAM) , the objective of the American Academy of Mechanics (AAM) is the advancement of the science and profession of mechanics.

The scope of AAM includes all of the disciplines involved in the modeling and study of the response of inanimate and animate matter to forces and environmental effects.

From Dr. Qizhi Xiao :

We are looking for several new permanent staffs, including software developers with solid background on mechanics and good programming skills. the detailed information about the posts can be found from

Two modes of thin film buckling are commonly observed, one with interface delamination (e.g., telephone cord blisters) and the other with no delamination (i.e., wrinkling). Which one would occur for your film?

The Air Force Office of Scientific Research (AFOSR) of the U.S. Air Force Research Laboratory (AFRL) and National Science Council (NSC) in Taiwan are pleased to announce that the 4th U.S. Air Force/Taiwan Nanoscience and Nanotechnology workshop will be held on February 8-9, 2007 at the main campus of the University of Houston. We invite you to join us at the workshop.

In response to a proposal by Zhigang Suo in November 2005, the Executive Committee of the Applied Mechanics Division (AMD) of ASME has created a new Technical Committee on Integrated Structures. The main purpose is to provide a home at AMD for those who are working in the interdisciplinary areas involving applied mechanics and integrated materials/structures such as microelectronics and biomedical technologies. Read more here.

To forge the link between academia and industries, the committee will be co-chaired by industrial and academic members. For the first year, Jun He of Intel and Rui Huang (myself) have served as the co-chairs. As the 2006 ASME Congress (November 5-10) coming around the corner, we would like to draw your attention to our first activities at the congress.

The American Academy of Mechanics calls for nominations for two awards from its members:

The 2006 American Academy of Mechanics Outstanding Service Award

Preliminary nominations should consist of a one-page letter describing the outstanding service of the nominee to the Academy as well as to the profession, along with a one-page biographical sketch of the nominee, together with the names of at least three people willing to write letters of support in the event that the Awards Committee requests them.

The 2006 American Academy of Mechanics Junior Award

A recent discussion here about the effect of surface stress on vibrations of microcantilever has gained some interest from our members. A few years ago, Zhigang and I looked at surface effect on buckling of a thin elastic film on a viscous layer (Huang and Suo, Thin Solid Films 429, 273-281, 2003). Although the physical phenomena (buckling vs vibrations) are different, the conclusion is quite consistent with Wei Hong and Pradeep's comments toward the end of the discussion. That is, surface stress only contributes as a residual stress and thus does not affect the buckling wavelength (frequency in space in analogy to frequency in time for vibrations).

I like to keep the mindset of being a student, learning from all sources on all topics I am interested. Recently I have learned quite a lot about mechanics and mechanicians from Applied Mechanics News and its sister blogs and now iMechanica.

With a job as an assistant professor, I always try to motivate my students to become future mechanicians. For this reason, I started Modeling Place as a group blog in January and gently forced my students to participate. Out of the five students I have, two actively participate by posting frequently, two occasionally post, and one dropped out quickly after one post. Together, the blog has been doing reasonably well, in terms of both quantity and quality of posts.

I learned a few tricks in handling images and got to know some interesting works in the general area of mechanics. How about the students? What benefits have they received? I have to ask them. For one, I awarded one student with a little gift as the best post of the semester. More importantly, I believe that they are reading more than they used to do, thus gaining broader knowledge and interest in mechanics and related science. They not only read the posts in the blog but also read from other sources (online or not) to find something to post. Furthermore, they have a place to practice writing. It is a big step from reading to writing, not only for foreign students I think.

It may be still too soon to tell how well this works, but the students themselves should be able to tell us more. If you are a student, I encourage you to comment on this to tell the professors what you like or don't like about iMechanica. At this stage of development, much more features and benefits can be accomodated. Your ideas could shape the future of iMechanica and benefit all students and those considering themselves as students of life.
