I have posted a movie showing a ring expansion experiment. A thin aluminum ring is made to expand through electromagnetic interaction at strain rates of about 10^4 per second. As the strain increases, numerous necks and fragments appear.
Resonance is a journal of science education published by the Indian Academy of Sciences for the past twenty years or so. As the introduction page states,
Let's contribute in a bit more educational topic!! If I want to mention two unique properties of the iMechanica, I can say iMechanica is a place where an alive discussion about popular topics of the mechanics going on every day and non stop. So this improves new ideas and as a consequence build some platforms for future research topics in the mechanics world. For me as an student, there is another beneficial and that is some courseworks or lecture notes which I download regularly. These handouts prepared by very expert scientists and are so useful. I appreciate this activities and I am very grateful to all people who also update the educational part of the webpage. Here is a new topic which with your help and comments can improve this part more and give it serious role to play here. Would you write about the summer schools which you are going to have in your universities and institutes located all over the world this summer? The summer schools is a point of interest among all students, specially if the topic will be about mechanics, modelling and simulation, nanomechanics and specially biomechanical issues. Also I will be very pleased if you will recommend the conferences you are going to hold or you like to introduce to student's section. That is another point which will be very useful. I am sure that it will be interesting for other members also. I am waiting for all your helps and news about "summer schools" and other "educational activities" running by you or your universities. I wish you all the best. Thank you.
Dear friends and colleagues,
We will be organizing a GEM4 Summer School on Cell & Molecular Mechanics in Biomedicine (with a focus on Cancer) at the National University of Singapore from 25 June to 6 July 2007. It will also be held in conjunction with the GEM4 Conference on Cancer to be held from 1 to 6 July 2007.

As well pointed out by Journal Club of March 2007, the flexible electronics is an emerging technology.
dear Imechanica users,
a wonderful location for our annual italian conference in stress analysis -- see www.aias2007.it. It is organized by our collegues in Università di Napoli, Prof. Renato Esposito. Attached the call for papers in PDF, and more info are below.

I was surprised several years ago when delving into the literature to not find any references about addition of nanoparticles to ice, to study their impact on the mechanics of ice. In short, to make nanocomposites where the matrix is ice. So, with 2 high school students from IMSA, the Illinois Math and Science Academy, we set about (with their limited time for a bit of research) to try adding some nanoparticles to water and to freeze it. The students simply used their home freezers to do this, and their mechanics measurements were with a hammer and chisel...
Simpleware Ltd., the world leader in image-based meshing software, has signed an agreement with Gaitech International Ltd. to resell the Simpleware suite of software products in China, Hong Kong, Taiwan and Macao.
Simpleware software offers an advanced solution to problems that were previously intractable due to the complexity in geometry reconstruction. Simpleware's technology has opened up numerical analysis (CFD and FEA) to a variety of applications, including biomedical engineering, material characterisation and industrial reverse engineering.
We extend the pioneering work of J.E. Hirsch, the inventor of the h-index, by proposing a simple and seemingly robust approach for comparing the scientific productivity and visibility of institutions. Our main findings are that i) while the h-index is a sensible criterion for comparing scientists within a given field, it does not directly extend to rank institutions of disparate sizes and journals, ii) however, the h-index, which always increases with paper population, has an universal growth rate for large numbers of papers; iii) thus the h-index of a large population of papers can be decomposed into the product of an impact index and a factor depending on the population size, iv) as a complement to the h-index, this new impact index provides an interesting way to compare the scientific production of institutions (universities, laboratories or journals).
