Through our productive collaboration and his scientific guidance, he managed to set high research standards in the framework of this Ph.D. Dissertation. I consider myself privileged working with him and I would like to express my deepest appreciation. I also gratefully acknowledge my colleague and friend Ph.D. Candidate Metsis Panagiotis, with whom I've spend countless hours discussing constructively several scientific subjects. Moreover, I would like to thank him for his great support and altruistic help which was priceless. Following, I would like to thank the other members of my thesis committee, Professor Michail Cotsovos and Assistant Professor Christos Zeris, for their helpful discussions and scientific comments. Their valuable comments and suggestions contributed to the improvement of the quality of this Dissertation . My research has been stimulated through the contractive comments of Professor Vlasis Koumousis and Associated Professor Konstantinos Spiliopoulos to whom I would like to express my appreciation. The comments and suggestions of the 7-member committee and especially those made by Prof Kappos, were very constructive. Their contribution is greatly acknowledged. I would also like to thank the Dr George Stavroulakis for the constructive and interesting collaboration that we had at the framework of the research team of prof. M.Papadrakakis. In addition, I would like to acknowledge Dr Michalis Fragiadakis, Dr George Lykidis, Dr Aristidis Papachristidis and Ph.D. Candidate Konstantinos Papanikolopoulos for their helpful suggestions during the Ph.D. Dissertation . During this research, two Diplomas and a Master Thesis were performed by Stefania Vasilomichelaki and Panayiotis Karakitsios whose rigorous work managed to provide significant conclusions through the parametric investigation of the finite element analysis code that was developed in the framework of the present Dissertation. I would like to acknowledge their contribution and thank them for the enjoyable and constructive collaboration. Furthermore, I would like to thank Professor Kyriakos Giannakoglou, Lecturer Dimos Charmpis, Dr Dimitris Koumpogiannis and Dr Zacharias Mouroutis for the excellent collaboration that we had during my Diploma, Master and Ph.D. research work on fluid- structure interaction problems. iii Acknowledgements Athens, Jan 2011 I would like to thank all my colleagues that worked in the research team of Professor Manolis Papadrakakis for their useful suggestions and comments thus maintaining a productive and pleasant environment. Finally, I would like to thank my wife Marina for her unfailing support during this Dissertation. She always encouraged me and never stopped believing in me, for which I will always be grateful. Thank You!

  • Argyris-Einstein Link
    The Argyris-Einstein Link As we enter a New Year, why is it that the UK has lost its way economically since we created the first Industrial Revolution that propelled our nation into the most powerful economic country in the World? In determining this decline we have to ask the question, what have the two men below got in common with the third person? One is the greatest scientist of the 20 th century Albert Einstein, the other debatably the greatest mathematician of the 20 th century Constantin Carathéodory (or stated as Konstantinos Karatheodoris by some) and the third person John Argyris, the late founding chairman of the World Innovation Foundation and cited by the USA’s greatest ever structural engineer Ray Clough as the inventor of the Finite Element Method in his 1960 publication “The Finite Element Method in Plane Stress Analysis”. Einstein – The 1 st man Carathéodory - The 2 nd man & Einstein’s Great Mentor’ Carathéodory the great mathematician who The Carathéodory/Einstein’s minds combine together gave Einstein the fundamental knowledge for to unravel the universe and time itself his Great theories in many ways (http://www.mlahanas.de/Greeks/new/Caratheodory.htm ) Argyris – The 3 rd man Professor John Hadji Argyris at the forefront with FEM world’s leading finite element engineers, Professor Ray Clough (white circle) and next to him, Professor Olgierd Zienkiewicz (blue circle) Introduction So what has this article to do with Britain’s economic decline? In this respect it is an overview of a single engineer whose work has literally transformed the world of engineering but where the UK ‘Establishment’ does not know or understand the great economic worth and benefit that engineers can bestow upon a nation.

  • John Argyis Obituary
    INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING Int. J. Numer. Meth. Engng 2004; 60:1633–1637 (DOI: 10.1002/nme.1131) OBITUARY JOHN ARGYRIS John Argyris, Professor Emeritus, Stuttgart University and University of London, died on 2 April 2004 in Stuttgart at the age of 91. Born on 19 August 1913 in Volos, Greece, he was educated in Civil Engineering at the Technical Universities of Athens and Munich. He then assumed a position in industry (J. Gollnow & Son, Stettin) where, between 1937 and 1939, he carried out theoretical and experimental research and worked on the design of steel and light alloy structures. In 1941–1942, he took a post-graduate course in Aeronautics and Mathematics at the Technical University of Zurich. He was with the Royal Aeronautical Society from 1943 to 1949 and at the University of London, Imperial College of Science and Technology, as Senior Lecturer in 1949, Reader in the Theory of Aeronautical Structures from 1950 to 1955 and Professor of Aeronautical Structures between 1955 and 1975. He was appointed Professor at Stuttgart University in 1959, acting as the Director of the Institute of Statics and Dynamics of Aerospace Structures between 1959 and 1984, and was subsequently Director of the Institute of Computer Applications from 1984 to 1994. When Professor Argyris started in Stuttgart, he was decisively involved in establishing the new Faculty of Aerospace Engineering and making it as advanced as possible: not élite, but outstanding in education and research. After the basic courses, a small select number of motivated students was educated in the most relevant disciplines, such as Aerodynamics, Thermodynamics, Aircraft Propulsion, Aircraft Construction, and Structural Analysis.

ARGYRIS 1913-2004 Elected in 1986 “For outstanding pioneering and continuing contributions in computer mechanics over a period of more than 30 years.” BY THOMAS J. R. HUGHES, J. TINSELY ODEN, AND MANOLIS PAPADRAKAKIS SUBMITTED BY THE NAE HOME SECRETARY JOHN H. ARGYRIS was a person with great vision, class, and persuasion, who dramatically influenced computational engineering and Science and who will be long remembered as one of the great pioneers of the discipline in its formative years. He passed away quietly on April 2, 2004 after respiratory complications. John rests in peace in Sankt Jorgens Cemetery in the city of Varberg, 60 km south of Goteborg, Sweden, near Argyris’s summer house. John was born on August 19, 1913, in the city of Volos, 300 km north of Athens, Greece, into a Greek Orthodox family. His father was a direct descendant of a Greek Independence War hero, while his mother came from an old Byzantine family of politicians, poets, and scientists, which included the famous mathematician Constantine Karatheodori, professor at the University of Munich. Volos, as it was during his childhood, remained very much alive in his memory, especially the house he grew up in. He vividly remembered, until the end, details of the room where, at the age 2, he almost died from typhoid fever.
