Research Scientist Positions (in Singapore)
-
The Institute of High
Performance Computing (IHPC), a member of the Agency for Science,
Technology and Research (A*STAR) in Singapore, invites applications for
eight available positions for research scientists in the field of
theoretical and computational mechanics and materials science. These
positions are in conjunction with the A*STAR-sponsored Visiting
Investigatorship Program (VIP) led by Prof. Huajian Gao from Brown University who is the Principle Investigator.
Influence of depolarization field on polarization states in epitaxial ferroelectric thin films with biaxial misfit strains
Depolarization field and misfit strain are two important factors that may greatly influence the properties of ferroelectric thin films. The effect of depolarization field on polarization states of single-domain ferroelectric thin films with nonequally biaxial in-plane misfit strains are studied in the present work by numerically solving three coupled Euler-Lagrange equations, which are derived from the minimization of total free energy.
Biomolecular detection by a cantilever functionalized by RNA aptamers as receptor molecules
We have recently reported the label-free detection of HCV (Hepatitis C Virus) helicase by using a resonating microcantilever whose surface is functionalized by RNA aptamers as receptor molecules. This work was accepted for publication at Biosensors & Bioelectronics.

OOF
I recently came across this free software - OOF2 on the nist website: http://www.ctcms.nist.gov/oof/oof2/index.html I was basically looking for analyzing the effect of microstructure on the stresses in coatings, and a friend of mine mentioned this software. Since it works only on Unix or Linux (and Mac) I have not been able to install it on my PC...Have a Mac on which i will try it out soon. Will post my experience when I start using it. In the meantime wanted to know what kind of problems others tackle using this software.
Kinetics of phase transformations in the peridynamic formulation of continuum mechanics
Abstract
We study the kinetics of phase transformations in solids using the peridynamic formulation of continuum mechanics. The peridynamic theory is a nonlocal formulation that does not involve spatial derivatives, and is a powerful tool to study defects such as cracks and interfaces.
Thin plate theory...
Hi all!
I have a small doubt in the assumptions made in thin plate theory.
We make some of the following assumptions in thin plate theory (Kirchoff's classical plate theory) (KCPT).
[1] The normal stress (out of plane=> sigma(z)) is zero. and
[2] The vertical deflection 'w' is not a function of 'z' => dw/dz = 0
Now there are three stress components sigma(x), sigma(y) and sigma(xy). The other three stress components sigma(z), sigma(xz) and sigma(yz). This is like a plane stress.
