Darko Jagarinec, born 1986, graduated with a BSc Degree from the University of Maribor, Faculty of Mechanical Engineering, Slovenia, in 2010. He continued to study at the same faculty as a PhD student. In the same year, he started working in the company Metalna IMPRO d.o.o. in Project Department for pressure vessel. His main research and work areas are fracture mechanics and pressure vessel design.

Peter Kirbiš, born 1989, is currently working as a doctor candidate. His work experience centers around metallographic/failure analysis and characterization of metals using various techniques with an emphasis on “in situ” electrical resistance measurements. His research is focused towards phase transformations in steels, with special attention towards the bainite reaction at very low temperatures, as well as welding and continuous casting of high carbon steels.

Assoc. Prof. Dr. Jožef Predan, born 1976, graduated with a BSc Dregree from the University of Maribor, Faculty of Mechanical Engineering, Slovenia, in 1999. He continued to study at the same faculty and completed his PhD in 2005. He is employed as an assistant and researcher at the same faculty. His main research areas are fatigue and fracture testing and analysis of fracture behavior of welded joints (especially strength mismatch of welded joints, heterogenous and also lamellas materials), Finite element analyses of homogeneous and inhomogeneous materials, especially fracture mechanics of 2D and 3D cracks.

Tomaž Vuherer, born 1970, graduated with a BSc Degree from the University of Maribor, Faculty of Mechanical Engineering, Slovenia, in 1999. He continued to study at the same faculty and completed his MSci in 1999. He continued work and study at the same faculty and completed his PhD in 2008.
