PREFACE
Most of the work presented in this thesis was carried out within a national research program in
Sweden, “Life Prediction Certification and in Service Assessment posite Structures”,
between July 1995 to July 1998 at Saab AB and at the Royal Institute of Technology,
Department of Aeronautics. It was financially supported by Saab and NFFP, the National
Aeronautical Research Program in Sweden, for which I am very grateful.
Most of the work carried out in this dissertation stems from research ideas formulated within
that program in which I had the privilege to act as a project leader. Participating parts where
besides Department of Structural Strength and Loads Technology at Saab AB, the Aeronautical
Research Institute of Sweden (FFA) and the Royal Institute of Technology, Department of
Aeronautics (KTH).
I would like to thank my supervisor Professor Anders Blom at the Royal Institute of
Technology for his support and encouragement during the course of this study and Professor
Jan Bäcklund for the opportunity to carry out this work at his department. Joakim Schön, at the
Aeronautical Research Institute of Sweden, is also greatly acknowledged as a friend,
companion in the project and as a valuable discussion partner. At the same institute I would
also like to thank Dr. Börje Andersson for his enthusiasm and deep knowledge, especially in
computational mechanics, which enabled us to perform state-of-the-art calculations with his
developed hp-adaptive FE-system STRIPE. I am also very grateful for the support received
from colleagues at Saab AB, especially Tomas Ireman, Christina Altkvist, Magnus Friberg and
Anders Bredberg at posite group but also to Hans Ansell, previous manager of the
department and co-autho
