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:

Hello all,
I am Nilesh and doing
study of Continuum damage mechanics, in that context, I have some doubt s
Can anyone tell
me?
1. As in plasticity we have yield surface and in damage we have damage surface but in this case, does damage surface working same ( for
isotropic and kinematics damage???? ) Like in isotropic and kinematic
hardening??? I mean expansion and movement for isotropic and kinematic damage
case???
applications of maths in the study of fractured surfaces
Forums
Hello everybody,
Please recommand me bibliography or the links on the WEB concerning the applications of different maths in the study of fractured surfaces. Thank you very much. In my country, Romania this domain is not know very well. Best regards from Romania!
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.

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

Lateral Force Microscopy
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?
