Acknowledgment
Completion of the research presented in this work was the result of efforts by many people to
whom I owe much appreciation. First, I would like to express my heartfelt appreciation and
gratitude to my advisor Professor Volnei Tita (São Carlos School of Engineering, University of
São Paulo) for providing me with endless encouragement and guide me through multitude of
challenges. I am sincerely grateful for his supervision and support throughout my doctoral
studies. I would like to thank you Prof. Dirk Vandepitte (Katholieke Universiteit Leuven) for
accepting the proposed work to be carried out at the KU Leuven and for his supervision and
support during the Belgium time. I would like to thank you Prof. Rui Guedes, Prof. Mario Vaz
(Faculty of Engineering of University of Porto) and Prof. Hernani Lopes (Instituto Politécnico
do Porto) for helping with the shearography tests.
I would like to thank you Prof. Marcelo Leite Ribeiro (São Carlos School of Engineering,
University of São Paulo) for your friendship and help, as well as for the ABAQUSTM license.
Also, I would like to thank you Prof. Elmer Gennaro (São Paulo State University) and Prof.
Romeu Rony (Federal University of Technology – Paraná). I also would like to thank my
colleagues in our research group for their friendship and hours of useful discussions. They are
André, Andres, Daniel, David, Douglas, Felipe Eloy, Felipe Rendeiro, Gregório, Jonathan, José
Augusto, Marcel, Murilo, Tarcísio, Vagner, Wander, Willian from Brazil, and Andy, Frederik,
Roland, Ruben from Belgium.
I would like to thank my family, especially my wife Ângela, for putting up with me during this
process and giving me valuable critics that helped immensely.
Finally, I gratefully acknowledge the partial support in Brazil by the Sao Paulo Research
Foundation (FAPESP process number: 2012/01047-8) and in Belgium by the Coordination for
the Improvement of the Higher Level Personnel (CAPES process number: 011214/2013-09). I
also would like to thank Navy Technological Centre (CTM – Brazil) for manufacturing
specimens.
