Tim Dabbs: subthreshold indents

I have recently obtained (courtesy of Brian Lawn and Robert Cook) a pdf copy of Tim's PhD thesis and have posted it on my web site: glass-fracture.org.
Tony Fisher-Cripps provided Tim's web site: (http://members.optusnet.com.au/timbaigl/dabbs.htm)  but the email address listed there does not seem to work.  If anyone has his email address please let me know.

Thanks,

Chuck
Since I originally posted the above, I learned that Tim's email has changed to: tdabbs@optusnet.com.au.

He has graciously provided a high resolution copy of his thesis and it has replaced the original I crude copy I had on my site. This is a very important piece of work.  Although Tim published a lot of this, a lot has remained unpublished and is contained in the thesis.

UGSC Research Strategy Workshop in Savannah, Georgia

A meeting will  be held in Savannah Georgia on Thursday and Friday, April14&15.

The purpose of the meeting is: " To enable the development   of ultra-strong glass products through pre-competitive fundamental research on usable glass strength: to educate the next generation of glass researchers: and to develop the tools and measurement techniques essential for the advancement of glass science".

The results will be reported here.

email alerts!

Some years ago I set up a website and a Blog to 'publicize' and share info about strength activities in glasses.  While there is generally some traffic on the web site, there is little on the Blog.  I have just posted a 'New Year's Greeting' and hope to see some activity result from that.
What I would like to do is to suggest that you each add 'Google reader' to you computers.  This will allow email alerts when a new post appears on the Blog.
I will be sending you each a separate email to tell about this.

Happy Holidays, etc.

For me 2010 has been a relatively productive year. In addition to general research initiatives and collaborations relating to strength, indentation behavior and stresses in glasses, activities with GMIC have been productive.

The 'UGSC' is in the process of setting up! This is the 'Usable Glass Strength Consortium'. For more information about this, please go to: gmic.org and more specifically to: http://www.gmic.org/Strength%20In%20Glass.html.
I would encourage all of you to become involved with this. Although it was started by the GMIC in the U.S, it is clearly meant to be an international effort. Have a look and see what part you can play!!!

In research terms, the setting up of the Abrio stress birefringence instrument with Prof. Satoshi Yoshida (in Shiga, Japan) and his student Sohtaro Iwata has been a landmark. Already very important results on ball indentations have been obtained. It is hoped that these studies will be extended to include the effects of coatings and surface stresses and surface condition on ball indentation stresses.

The more general activities of the year are indicated on my web site: glass-fracture.org.

Additional collaborations with Prof.S. Chandrasekar and Dr. Narayan Sundaram at Purdue University related to contact stress calculations as well as other experimental studies related to surface damage have been initiated this year and are being actively pursued.

I encourage all of you to take an active part in the building of this blog into a useful 'information exchange' medium.

Happy New Year.
