Recent papers on rubber mechanics
Here are some of my recent papers about mechanics of rubber material. They concern constitutive modelling, fatigue and fracture.

Problems with atomic force microscopy
Hello,
Recently, I have a problem bothered me alot, anybody please help me out.
I am using Dimension 3100 AFM. It is a scanned tip SPM. There are two screws to adjust mirrow so that the laser can be reflected to the photodiode. My problem is:

Why do people become registered users of iMechanica?
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
Sih's Strain Energy Density Approach in Fracture - why is it not very popular?
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.
stress singularity and stress relationship
Dear All
Williams analysis is well known for stress singularity. Actually when we are analysing the stress distributions between two diffrent configuration which is given below ,based on the stress singularity, I got a doubt...how the order of stress singularity is directly related with the stress. (we can get the relationship using equation) however if i want to explain to a student who never come across with applied mechanics. How can we explain to him in very simple and understandable manner.

hi all,
i would like to know how can i find the error in a heat transfer problem with the help of
zienkiewicz zhu error estimator.
