Using Computational Biology to Bring Predatory Dinosaurs Back to Life

The proposed programme of research seeks to use state-of-the-art computational techniques to reverse engineer the walking cycle of a predatory dinosaur. Software for image-based modelling, parallel finite element analysis and evolutionary robotics will be coupled and deployed

Most cited papers and H-factor of some mechanics journals -- IJSS

Submitted by Mike Ciavarella on Thu, 07/17/2008 - 08:18

IMPORTANT UPDATE JULY 18

The full list of journals ranked by H index

It is possible to rank journals equally as authors, using e.g. the Harzing Publish or Perish sofware based on Google Scholar. I did the excercise for IJSS. It turns out the H-index is 78 (slightly higher than even the best authors in solid mechanics, but not stellar). In the most highlycited papers, we find good names, but not stellar papers.

The results may be affected by the limitations of the software.

elastic network model

structure-property relationship

We consider the mesoscopic model of protein materials composed of protein crystals with given space group for understanding the mechanical properties of protein materials with respect to their structures. This preprint was accepted for publication at Journal of Computational Chemistry.

Entropy production on a single trajectory of the small system

Submitted by Joseph X. Zhou on Wed, 07/16/2008 - 20:51

The following PowerPoint file is from the talk which I gave in my research group recently. It is also my understanding and reading notes from a serial of papers by Prof. Udo Seifert, in which he generalized the entropy production on a single trajectory of the small system such as a molecular machine. It mainly addresses three questions:

3D modeling of composite material in ANSYS

Submitted by Basak on Tue, 07/15/2008 - 21:52

Hi,

I am trying to model a composite material in ANSYS. I have used ANSYS for simple simulations before but I have never done composite material analysis. I have attached a simple schematic of what I am trying to model. Can you guys please help me? Any tip you can give will help. I have limited time.

Thank you,

Basak

Viscoelasticity in Abaqus

Submitted by Andreas Burger on Tue, 07/15/2008 - 18:25

Hi All,

I would like to use Abaqus to model the viscoelastic material behaviour of a polymer.

I have material data from a simple uniaxial creep experiment (nominal strain vs time). I tried to use the viscoelastic material model in Abaqus. I am a bit confused as to how I need to enter my data (what format).

The manual says I have to specify the normalized bulk and normalized shear compliance .

where is the shear compliance and the volumetric compliance

Puzzle: What caused this failure?

failure

Here's a puzzle for our readers. The following image is of the surface of a failed joint followed by a picture of the joint (not the same one but a similar one) before joining. What material is it? What caused the failure? All manner of speculation is welcome.
