The number of registered users of iMechanica is approaching 3000. This sustained growth has been surprising to many, considering that iMechanica was launched less than a year ago, in September 2006, that iMechanica uses an off-the-shelf open-source software, Drupal, and that everyone can read everything without registration. Why have so many people registered? There might be many reasons, such as
Most fracture classes and texts focus on the following different approaches: Griffith's energy approach, Irwin's stress intensity factor approach, the Barenblatt-Dugdale strip yield model (and subsequently, cohesive zone modeling) and Rice's J-Integral approach. As a graduate student studying fracture mechanics, I have often wondered why there seems to be very little discussion in the community with regard to Sih's strain energy density approach. Are there any fundamental limitations to the approach or are there "other" reasons behind this? Your thoughts are appreciated.
How can i make post doc. in another country?
How can i follow post doc positions available in europe or america?
This is either a wage question I am asking or a stupid one...
How many fracture criterion do we have and what are they? some of these criterion that I am reading are related or a form of others...For example CTOD (crack tip opening displacement) criterion is related to energy release rate in
" A CTOD-Based Mixed-Mode Fracture Criterion" by Fashang Ma et al.
Any guid or direct help would be much appreciated.
Thanks for your time

I would like to do lateral force microscopy on biological samples. The more I look into it, it seems it is very difficult to calibrate AFM tips for lateral force microscopy. Does anyone have any suggestions about how to calibrate tips and which tips are conducive for lateral AFM?
If you are interested by the mechanics of elastomers, there is a dedicated conference for you : ECCMR 5, which will be held in Paris, France, 4-7 September 2007.
It is the fifth edition of the European Conference on Constitutive Models for Rubber Conference. The call for paper is now closed, but registration is still open.

The National Science Foundation (NSF) has made a recent award to help increase graduate student participation at the Tenth Pan American Congress of Applied Mechanics (PACAM X). These awards will be made in the form of mini-travel grants ($500 - $1,000) for exceptionally qualified students to participate in PACAM X January 7-11, 2008, in beautiful Cancun, Mexico.
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.
Elsevier-bashing has become a sport among researchers. The company is singled out, among publishers of research journals, perhaps because it is the largest. We might as well use Elsevier as a representative of the publishers, and hard-working people at Elsevier should not be offended.
