ENVIRONMENTALLY ASSISTED CRACKING
AND HYDROGEN EMBRITTLEMENT

European Structural Integrity Society Technical Committee 10 (ESIS TC10) on Envi-
ronmentally Assisted Cracking (EAC) and the TC10 Subcommittee on Hydrogen Degra-
dation (HE) held a joint Workshop on “Environmentally assisted cracking and hydrogen
embrittlement” on 3 and 4 November, 2004, at the facilities of Venezia Tecnologie in Porto
Marghera (Venice). Venezia Tecnologie (VeTec) is a research laboratory which has been
structured to support industrial companies in their technological development.
TC 10 workshops are usually held during ESIS conferences, but sometimes they are
hosted by participating organization, such as is the case of VeTec. In fact, the need to
implement the activities of scientific working parties with the aim of a better use of modern
tools such as social networks and ICT (information and communication technology) is no-
wadays quite growing. However, implementation of tools is not effective if it is not coupled
with a cultural change that should be promoted by the activities of associations and/or wor-
king parties, such as TC10.
Dr. Wolfgang Dietzel, who was the Chairman of the Group since the beginning, and
Dr. Giovanna Gabetta who became co-chairperson since 1996 were both present; Prof. Hry-
horiy Nykyforchyn, Chairman of the TC10 Subcommittee, presented a paper via Skype.
Starting at the ESIS Council Meeting during the ECF 18 in Dresden in August/September
2010, the TC chairmanship was handed to Prof. Jesús Toribio from the University of Sala-
manca in Spain. In the recent years, TC 10 started to take up new EAC related tasks for
which the open and versatile structure of the group appears ideally suited. Knowledge Ma-
nagement and the solution of complex technical problems are new challenges that need to
be addressed, and the formation of new networks will play an important role in future. To
this aim, TC10 and its Chairman Jesús Toribio actively took part in the organization, by the
Italian, Portuguese and Spanish Group on Fracture, of the Multilateral Workshop on “Frac-
ture and structural integrity related issues”, held in Catania, Italy, on September 15–17, 2014.
The Workshop Program included the following presentations:
G. Gabetta “35 years in EAC – What is left?”; W. Dietzel “SCC of high strength
Aluminum alloys”; J. Toribio and V. Kharin “Revisiting continuum modeling of hydrogen
diffusion and trapping in metals”; H. Nykyforchyn and G. Gabetta “Experimental modeling
of in-bulk material degradation of main gas pipelines”; G. Meneghetti “Engineering estima-
tions of notch-stress intensity factors using the peak stress method”; G. Bolzon “The diag-
nostic capabilities of indentation tests”; D. Firrao and P. Matteis “Is 13 years too a long
time for an EAC gas bottle burst?”; R. Bermejo, C. Krautgasser, P. Supancic and R. Danzer
“Environmentally strength degradation of glass-ceramic composites: experiments and mo-
deling”; T. Matsuo, M. Endo and H. Matsunaga “Effects of internal hydrogen on the ducti-
lity of ductile cast irons”; J. Toribio, M. Lorenzo, D. Vergara and V. Kharin “FE numerical
analysis of hydrogen-assisted rolling-contact fatigue degradation in bearings for wind turbi-
nes”; M. Gentile and S. Fano “Pipeline sour service material selection: where are we?”;
L.Vergani, G. Gobbi and C. Colombo “A cohesive model to simulate hydrogen-assisted
cracking”; F. Berto and P. Gallo –“High temperature fatigue of notches components made of
structural steel”; A. Pontarollo “Experimental devices for EAC tests at ultra high pressure”.
Finally Prof. J. Toribio proclaimed the initiative: “Salamanca 2015: ESIS TC10 Con-
ference on Environmentally Assisted Cracking & Hydrogen Embrittlement and Degrada-
tion” .
