TC01 Update 2012

ESIS Meeting at Freiburg On 5th-6th December 2012 a meeting of the TC1 (whose activity was restarted in 2010 under the Chair of U. Zerbst and I Varfolomeev) was held in Freiburg. It has been a succesfull meeting, the list of presentation as well as the presentations can be downloaded here.

It was decided to publish a special issue of an Elsevier journal on the topic. The next meeting is planned for late spring 2013 in Portugal and will focus on crack closure effects and its description.
