Scientific potential of Croatia
- 6500 Doctors of Philosophy and 3000
Masters of science
- Only 1,43% of GDP for science and
education, whereas only 0,3% present
investments from the Croatian companies.
Building of Mechanical Engineering Faculty in Slavonski Brod
- Six Universities: Zagreb, Osijek, Rijeka,
Split, Zadar and Dubrovnik and a lot of
mainly state institutes, the biggest and
most known is Ruđer Bošković Institute.

Centres for data and document conservation
- Mechanical and physical testing centres are located mainly at
the universities (4 mechanical and 4 civil engineering faculties
(Zagreb, Rijeka, Split, Osijek, Slavonski Brod etc), at the
Institutes (RBI, Civil engineering institute etc) and in the
companies as well.
- the collaboration between the institutions in data and documents
exchanging within the state and abroad is in the rule very few.
- the first attempt to do something in this sense is the forming of
the database MAT-NET by Faculty of mechanical engineering and
naval architecture (FSB) in Zagreb.
6/15
Mechanical Engineering Faculty in Slavonski Brod, Croatia
MAT-NET database consists:
- catalogue of all Croatian institutions dealing with materials
- new books, papers, texts
- info service (conferences, workshops, seminars, events related to the
materials matter)
- advertising of companies
- news from the field

Data management and dissemination in nuclear safety
- Croatia and Slovenia have common
nuclear power plant Krško, situated in
Slovenia near border with Croatia.
In project ‘Application of fracture
mechanics by revitalisation of energetic
components’ participate the researchers
from Ljubljana, Zagreb, Maribor and
Slavonski Brod.
The aim of the project is to define the
procedure for structural integrity
assessment (based on SINTAP) and the
life cycle estimation of some vital part of
the power plant.

Some results achieved at the project devoted
to the fracture mechanics application:
Experimental determination of the critical value of
LEFM and EPFM parameters (KIC, CTOD, CMOD,
J-integral) for homogeneous and heterogeneous
cracked components (f. i. welded and adhesive
joints)

•
Modelling and numerical calculation of fracture
toughness parameters by finite element (FE)
analysis, stress and strain distributions,
structural optimisation etc.
CDF and FAD determination and critical crack
value estimation
Life cycle estimation of some components by
using of SINTAP procedure
Stress field by T-joint of pipes
Equivalent stress distribution by spherical pressure vessel

Recent investigations:
Bilateral Croatian-Hungarian project 'New approach to design of welded components
based on benefits of present heterogeneity in the weld joint' together with Báy Zsoltan
Institute for Logistics and Production Systems - Miskolc, prof. László Tóth.

Recent investigations:
The results of the project‘Object
grating method application in
strain determination on CTOD
test' will be published in the
International Journal for Strain
in May 2006.
The fracture behaviour is
described by measuring
deformation on surface of
specimen in term of CTOD and
consenquently by strain
determination.

crack tip at different load of specimen

Instead conclusions
 Most of the laboratories in Croatia are not accredited according to the EN 17025 and
therefore obtained results could not be fully accepted.
 Experimental data for different materials, coatings and joints as the result of
investigations performed by companies, especially in the case of nuclear power plants are in
the rule confidential and not public.
 Dissemination of public data and documents for projects supported by Ministry of
Science, Education and Sport of Republic of Croatia concerning the mechanical and
physical testing of materials are highly released for public access. Most of data could be
found using the Internet searching the database with projects reports (http://bib.irb.hr).
 There is no official online data and information network in Croatia, but some efforts have
been done with the MAT-NET database funding, where each institution (university, company,
institute) could be registered and researchers can access the newest information from the
field (conferences, original papers, popular texts etc), but there is no possibility to entry
some experimental data.

 Therefore, Croatian universities and R&D organisations are really interested in to learn
how to use web-enabled databases and they would become the part of the created network.
 We would be very honoured if we could be invited to join JRC in some of the new project
proposals to EU framework programmes with the topics of managing engineering data.
