Web 2.0 and Medicine
I stumbled across this interesting blog post yesterday concerning an upcoming course on medicine via web 2.0. It appeared quite interesting from several perspectives: first, medicine is often associated with being behind the times on technology but this all looks pretty current, secondly it may be the most comprehensive listing of topics I have seen where web 2.0 is applied to a single discipline, and finally it made me wonder what more we could do with mechanics via web 2.0 beyon
Effect of Surface Morphology on the Stability of Thin Nanostructures
We have recently studied the atomic scale structural stability of
freestanding wavy gold (Au) nanofilms using molecular dynamics
simulations. In recent years, wavy or patterned structurs have shown great promise for applications in various emerging technologies including fuel cells
engineering, tissue engineering, biomedical engineering, creation
of counterfeit-resistant documents , nanolithography in microelectronics, optoelectronics, nanomachinesand many others. It is out of question that the success of these novel applications lies on one crucial factor – the
About a work on theoretical modeling
Hi
I am a graduate student at University of Alabama. I am working on Stochastic modeling of damage evolution. Recently I have finished the mathematical/theoretical modeling section. I haven't done any Numerical or FEA simulation or experimental analysis. In this first phase I emphasized on the mathematical formulation and some short proofs. I wish to submit this work to a relevent journal. Can anyone please let me know if there is any suitable journal for this kind purely theoretical as well as solid/applied mechanics work related to stochastic modeling of damage mechanics?
Energy Balance Invariance for Interacting Particle Systems
This paper studies the invariance of balance of
energy for a system of interacting particles under groups of
transformations. Balance of energy and its invariance is first
examined in Euclidean space. Unlike the case of continuous media,
it is shown that conservation and balance laws do not follow
from the assumption of invariance of balance of energy under
time-dependent isometries of the ambient space. However, the
postulate of invariance of balance of energy under arbitrary
Crack propagation in ABAQUS for a mode II kind of crack opening
I am modelling a system subjected to a thermal shock, where in there are both vertical cracks (mode I ) and also infacial cracks (cracks that primarily fail by delaminaton-mode II)
For vertical cracks, Iam able to get reasonable answers for mode I crack propagation in ABAQUS using a critical crack opening displacement criterion. However when it comes to interfacial crack, I dont know how to propagate it becz all the criterion in the debond subroutines in abaqus assume a mode I kind of crack opening.
Is my assumption wrong ? Can anyone help me out in this?

Invalid Geometry Problem!!!!
Hi all
I have posted two posts before and NO BODY has REPLIED to my questions....
please i need some help with my ABACUS....I have my data and whenever i run my data on ABACUS it says INVALID GEOMETRY...
If any any one knows how to solve this as i have tried searching the web and go through tools---> repairs and still not working...
Thank you
Nina
