Invited talk to the ASTM E08.06.05 Subcommittee on Elevated Temperature Crack Growth, 12th May 2021, 12:00-1:00pm EST, WebEx. The main is to address future standardisation of TMF CG test techniques as shown in the agenda.
Workshop on Interregional Collaboration for Sustainable Aviation, was organised at Clean SKy 2, Brussels, 23 January 2020, https://www.cleansky.eu/news/regional-cooperation-key-for-achieving-clean-sky-objectives. The main aim was to learn from the experience of other regions with the Clean Sky 2 programme and to foster interregional cooperation between European aviation regions. The workshop was organised by Jara Fisher, Economic Development Agency Brandenburg, and the project coordinator.
Seminars and meetings have been held (and will be held) with the The High Temperature Mechanical Testing Committee (HTMTC) and BAM to work towards standardisation of TMF CG experimental method. The DevTMF Code of Practice will be published under the support of the HTMTC and BAM. The HTMTC operates as Technical Committee 11 (TC11) of the European Structural Integrity Society (ESIS). The chairman of the HTMTC, Dr Hellmuth Klingelhöffer, is also the Convenor of the ISO TC164 SC4 WG6, Fatigue testing: elasto-plastic strain and crack growth conditions, https://www.iso.org/committee/53560.html.

S. Stekovic, et. al., High temperature mechanical properties of CGRR1000, workshop with Prof. Cathie Rae from the University of Cambridge (UK), Linköping University, September 2018. The aims of the meeting were to present DevTMF, discuss crack initiation and propagation behaviour of CGRR1000 and decide on future collaboration inside and outside the project.
Smart Specialisation workshops and seminars in area of advanced materials and manufacturing have been held with East Sweden regions, the Upper Austria, Linz, Austria, and the Emilia-Romagna region, Bologna, Italy. The events were attended by the project coordinator. The Region Östergötland strategi within advanced materials can be viewed here. The region has signed memorandum of understanding with Clean Sky 2 in Feb 2016. The project coordinator was a part of the project group receiving funding for infrastructure investment from the European Regional Development Fund, more information can be found here.
