In the attached pre-print, we investigate quantum confinement induced strain in quantum dots. This paper has been written keeping in mind the condensed matter physics/quantum dot community (accepted for publication in Phy.
They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid. Video was recorded at Barcelona, Spain.
I am trying to find out the theoretical adhesive strength limit of a few materials, or more precisely the ratio adhesive strength limit to elastic modulus. I think this is after all part of the Lennard-Jones constants potential - theoretical adhesive strength limit is simply the maximum of the curve.
The Drupal software we use for iMechanica makes the blog posts very wide. It may be a little uncomfortable to read from the far left of the window to the far right. With a window so wide, it's easy to lose your place in the reading in moving to the next line of text.
There have been several posts recently discussing new directions in computational mechanics. Here is a review article that appeared recently that may be of interest.

hi Nanshu Lu,
i'm savita jain. i have project some what related to your topic. can i have results of your final coparision of slip line and FEM solutions.please let me know about any progress in your work.
I work with AVI in my research so I have included a MATLAB implementation of AVI for the 1-D harmonic oscillator. The code will solve the equation a + gamma * v + (k1 + k2 + k3) x = 0 with any initial conditions x(0) and v(0). Here the spring constant has been artifically split into three spring constants to simulate multiple potentials. If there is only one potential AVI simplifies to the usual Velocity Verlet integrator. The friction term is absorbed into the k1 term in the implementation. The main idea in the implementation is to construct the propagation matrix for the system (x,v) for the different potentials.
Given the growing interest in poroelasticity within this forum, I thought I would post the link to "Poronet" -- the poromechanics internet resources network. In particular, there is a nice long pdf chapter on the fundamentals of poroelasticity from Detournay and Cheng, 1993, which has become one of the standard references in the field.
