Reports
ICTP - The 11th ICTP will be held in Atsuta-ku - Nagoya (Japan) from October 19th to 24th, 2014. It is organized by the Japan Society for Technology of Plasticity (JSTP). The host will be Prof. T. Ishikawa, Nagoya University, President of JSTP. A tentative list of Cooperating Organizations include JSPE, ISIJ, JIM, JSME, JILM, JBMA, ICEM, IISI, SMSJ, JSPPM, CIRP, ICFG, IDDRG, ITA, Nagoya City, Nagoya University Details on the event can be asked to Prof. Ishikawa (This email address is being protected from spambots. You need JavaScript enabled to view it.) and will be soon available in the conference website (reported by Prof.Kitamura).
With the aim of continuous improvement of the management of ICTP and especially of the quality of papers submitted for publication and presentation, professor M. Kiuchi, chairman of the ICTP, proposed the formation inside the ICTP of a “the task-force”. The members participants in this task force (M.Kiuchi as chairman, G. Hirt, A.E. Tekkaya, C.G. Kang, P.F. Bariani and K. Mori as secretary) will have a meeting during the GA-Part 2 in Hong Kong on Friday 24th August at 14.00. (reported by Prof. Kiuchi).
ICFG - The 45th ICFG Plenary Meeting will be held in Nagoya (Japan) from September 9th to 12th, 2012. The host will be Prof. T. Ishikawa, Nagoya University, and President of JSTP. The meeting will include some invited papers on trends and visions on cold forging by experts from industry as well as academia, Details are available in the conference website www.icfg2012.org (reported by Prof. Kitamura).

CIRP Terminology Committee and CIRPedia Section
Prof. A. Erman Tekkaya presented the terminology and CIRPedia Section. Questions were raised with respect of the benefits of having CIRPedia especially when ‘CIRP’ was removed from the title. Prof. Tekkaya briefed the history of CIRPedia, i.e., transferring the dictionary to the web. Although the original idea/intention was good, tremendous work is involved and the CIRP community has not received benefits. The members asked the vice-chair to raise a question about the value of the CIRPedia work at the Liaison committee.
Keynote Papers
Prof. Mori presented the progress report on the 2013 Paper-Session keynote paper “Joining by plastic deformation” by Prof. Mori, Micari, Fratini, Tekkaya, and Bay. Suggestions from attendees include: (1) providing a definition of plastic joining; (2) providing a balanced view of advantages and disadvantages of plastic joining in the introduction section; (3) providing more discussions on future outlook, i.e., telling what we do not know as well as what we know; (4) including the tool design in friction stir welding (FSW); and (5) utilizing the rich literature survey that is already existed in the area of FSW. Prof. Bruschi presented the outline of the 2014 Internal-Session keynote paper “Testing and modeling of material behavior and formability in sheet forming processes”.
Keynote Proposals for 2015
Prof. Tekkaya proposed “predicting and controlling product properties in metal forming processes”. The presentation is included in Appendix E. The proposal received unanimous support from the attendees. The scope of the keynote was discussed in terms of a balance between depth and breadth. It was concluded that only those properties affected by metal forming processes will be included. A special session on this keynote was requested to be organized in the next Paris meeting.
