Hi all.

I am modeling a problem of a Double Cantilever Beam in Ansys 11.0,

using Exponential and Bi-linear Cohesive Laws.

For the Bi-Linear law, Ansys needs to introduce 6 constants, like the Critical Fracture Energy Gc, the normal stress σ...

The fifth constant, η, is the artificial damping coefficient, introduced to improve the convergence to solution.

Can you help me to understand the nature of this parameter?

Which values of this damping coefficient must be considered for a good modeling of the problem?

Two new papers grabbed my attention on my long unread list of journal tables of contents in Google Reader. 

1) The first was

PNAS 106, 10103 (2009), doi:10.1073/pnas.0905193106, http://www.youtube.com/watch?v=dPJBalMZ824&feature=channel_page,    http://www.nanowerk.com/news/newsid=11108.php

A one-year post-doc is available in conjunction with

1) Prof. Asenov, University of Glasgow

2) Dr. Bordas, University of Glasgow/Cardiff

 to study the behaviour of nano-CMOS semi-conductors.

Please write to stephane dot bordas at g ma i l dot com 

 for details with your:

1) CV

2) Three references

3) a statement of why you are qualified and interested in this position

 You should

1) have a strong background in finite element methods

This position starts in July 2009 and lasts for 8 months.
