This work could not have been completed without the help of many people to whom I would like to give my thanks. I would like to express my deepest gratitude to Dr. Erian Armanios for his patient guidance throughout my life at Georgia Tech. This work would have never been possible without his immeasurable professional and emotional support, encouragement and above all his trust. I am also grateful to Dr. D. Stefan Dancila for his support in this work. His valuable critiques and guidance helped me improve my work. I also would like to acknowledge Dr. Olivier A. Bauchau. I am thankful to him for providing the DYMORE and VABS programs. I would like to thank Dr. Dewey H. Hodges and Dr. Abdul-Hamid Zureick for their willingness to serve on my thesis committee. This work has been completed under a grant from the National Rotorcraft Technology Center. I am sincerely thankful for their support. Additionally I would like to thank my officemates, true friends, Samer Tawfik, Xinyuan Tan and Dr. Roxana Vasilescu for their technical and emotional support. I sincerely thank my parents Nedime and Engin Ozbay. Without their love, support and sacrifices, I would not be who I am now. Thank you for your belief in what I could achieve eventually. Finally I would like to express my great gratitude to my lovely wife Tuba, for her unconditional love, support and confidence. It is a huge understatement to say that I could achieve this without her. I love her. The rest of my days are special because of her. v TABLE OF CONTENTS
