Personal data:

Dražan Kozak was born on July 31, 1967. He graduated from the Mechanical Engineering Faculty (SF) in Slavonski Brod, Josip Juraj Strossmayer University of Osijek in 1991. After that, he started with his postgraduate study at the Faculty of Mechanical Engineering and Naval Architecture (FSB), University of Zagreb. Simultaneously he has been employed at the SF Slavonski Brod, as the scientific novice. He achieved his titles Master of Science in 1995 and Doctor of Philosophy in 2001, both at the FSB Zagreb. Thesis research was focused on the fracture behaviour of strength mismatch welded joints with surface and/or through-thickness crack located in the middle of the weld and/or in the heat affected zone.

An academic career he started as an Assistant Professor in 2002, in 2005 he became Associate Professor, in 2009 Full Professor and in 2014 Full Professor with tenure in the field of Mechanics and Strength of Materials. Prof. Kozak is a lecturer in the courses as Engineering Mechanics I (Static) and II (Kinematics and Dynamics), Strength of Materials I and II, Numerical methods, Finite Element Method, Pressure vessels and piping and Fracture Mechanics at the Mechanical Engineering Constructions Department by SF in Slavonski Brod.

He was the main researcher on the bilateral international Slovenian-Croatian project (2003-2004) 'Application of fracture mechanics by energetic components revitalisation' and Hungarian-Croatian project (2005-2007) 'New approach to design of welded components based on benefits of present heterogeneity in the welded joint'. The results of the bilateral projects were implemented into structural integrity assessment of vital parts of the steam generator in Nuclear Power Plant Krško in Slovenia. Prof Kozak led also the bilateral Austrian-Croatian (2008-2009) project 'An influence of surface treatment processes on the fatigue behaviour under multiaxial loading' together with Dr-Ing Jürgen Fröschl (Montanuniversität Leoben). He leads together with Prof Aleksandar Sedmak bilateral Serbian-Croatian project (2010-2011) 'Integrity assessment and energetic efficiency of structures in exploitation'. He is the main researcher at the Slovenian-Croatian bilateral project (2018-2019) titled 'Fracture behavior of dental implants made from Ti-6Al-7Nb alloy with conventional processing in relation to the SLM processing' together with Prof. Nenad Gubeljak (Faculty of Mechanical Engineering, University of Maribor).

During the last years, he was actively included in the work on the fundamental national project 0152-018 'Life cycle assessment of the structures considering fracture mechanics approach', as a researcher. He was the main investigator on the project for young scientists 'Numerical modelling of strength mismatch welded joints with cracks' supported by the Ministry of Science and Technology of the Republic of Croatia (MZOS). Prof. Kozak was the head of the project 152-1201910-1909 'Analysis and fracture assessment of structures of anisotropic materials' granted also by MZOS. The aim of the project is to reach the best performance of structural components in order to ensure safe service of heterogeneous and anisotropic materials, especially in biomechanics issues. He is the coordinator of eight CEEPUS projects: CIII-RO-0202, CIII-BG-1103, CIII-RS-0065, CIII-PL-0033, CIII-RO-0058,  CIII-PL-0701, CIII-CZ-0201, and PL-0007. He was project manager of the project "ME4CataLOgue - Croatian Catalogue of knowledge, skills and competences for Mechanical Engineering studies based on learning outcomes" (2013-2015) which is co-financed by the European Union through the IPA IV component Human Resources Development. He was a team member at the EU project WORTH (2015-2016). He is an associate at the project supported by Croatian Science Foundation (HRZZ) IP-2014-09-1218 „Defining the possibility of application of mini dental implants (MDI) and their results in vitro and clinical prospective investigations“(2015-2019), and IP-2019-04-3607 „Modeling and simulation in the development of advanced materials“(2019-2023), as well.

Dr Kozak attended courses or had scholarships for a short-time visit to Hochschule Bremen (1992 and 1994), TU Vienna (1993 and 2002), CISM Udine (1992 and 1998), University of Sheffield (1998), University of Maribor (2001), MPA Stuttgart (2003), NATO Advanced Research Workshop in Budapest (2003), Enlargement and Integration Workshop JRC Petten (2005, 2006 and 2011), FITNET 3rd Training Seminar Miskolc (2005), ESF-ORI Conference in Lisbon (2007), Faculty of Engineering in Baia Mare (2009), TU Sofia (2010), TU Poznan (2010), CAMPUS 02 Graz (2011, 2014 and 2019), VŠB TU Ostrava (2011 and 2013), TU Cluj Napoca (2012, 2014, 2016, 2018), Transilvania University of Brasov (2013), University of Oradea (2014), TU Cracow (2015), University of Pannonia (2017, 2018) and TU Gliwice (2019). In the framework of the ERASMUS staff mobility program, he taught at the Faculty of Mechanical Engineering, University of Maribor in the academic year 2009/2010, and he was at the Istanbul Aydin University in Erasmus preparatory visit (2012).

He published over 100 scientific-research papers at the Conferences and more than 75 articles in Journals mainly devoted to structural integrity assessment. He published 103 articles in impacted Journals referred to the Web of Science databases, which are 580 times cited (Web of Science Researcher ID: AAG-5800-2019). His h-index in WoS is 13.

Prof. Drazan Kozak was the Vice-Rector for education and students at the Josip Juraj Strossmayer University of Osijek (2017-2020) and the Dean at the native Faculty - SF (2009-2013), and Vice-Dean for science at the SF (2005-2009). He is an honorary professor at the GAMF Kecskemet college, Hungary, and guest professor at the Faculty of technical sciences, University of Novi Sad, Serbia. He is a member of ESIS (President of Croatian branch), ASME (ASME Membership Number is 100092830), and acts as a member of the Croatian Society of Mechanics.
