How do I resize my window for easier reading?
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.
Large-scale hierarchical molecular modeling of nanostructured biological materials
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.

es 246 project:plane strain extrusion- slip line field solution vs.FEM solution
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.
MATLAB Implementation of AVI
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.
Poroelasticity references
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.
Stress or strain: which one is more fundamental?
In between stress and strain, which one is the more fundamental physical quantity? Or is it the case that each is defined independent of the other and so nothing can be said about their order? Is this the case?
Cycle Sequence of Fatigue Crack Initiation and Growth at the Submicron Scale
I recently used focused ion beam to fabricate some small structures, such as free-standing micro-beams, in LIGA Ni thin films and applied cyclic loads to those small micro-beams. In such a way, dynamics of fatigue crack initiation and growth can be revealed. Part of my results has been attached with this post.
