Preface
This licentiate thesis presents work that has been carried out at the Division of
Structural Engineering, Department of Civil and Mining Engineering at Luleå
University of Technology (LTU). The work has mainly been funded by the Swedish
National Rail Administration, LTU and European Rail Research Institute (ERRI), the
Netherlands.
First, I would like to thank my supervisor, Prof. Tech. Dr. Lennart Elfgren, head of the
division, for being a valuable source of knowledge and enthusiasm. Further, I thank
Ass. Prof. Tech. Dr. Ulf T. Ohlsson and Prof. Tech. Dr. Thomas Olofsson for always
having time for discussions. I would also like to thank Tech. Dr. Hans Hedlund and
Tech. Dr. Patrik Groth for all their advice and support during my time at LTU and
Ass. Prof. Tech. Dr. Mats for “bringing” me back to LTU and PhD studies!
I would like to express my gratitude to the staff at Testlab, Mr. Håkan Johansson (head
of “Testlab”), Mr. Danielsson, Mr. Lars Åström and Mr. Mikael Kågström.
They have performed, helped and advised me during all the tests/experiments. In this
context I will also mention MSc. Jörgen Andersson who performed all the fatigue tests
while working with his master thesis.
Moreover, I owe a debt of gratitude to the rest of the staff at the Division of Structural
Engineering for making
