Mechanical Vibrations / Foundations of Engineering Mechanics (PDF)

György Szeidl was born in Esztergom (Hungary) on September 8, 1942. After graduating from the Pelbárt Temesvári Catholic High School in 1960 I worked for the Machine Tools Factory of Esztergom till 1962 when I was admitted to the Mechanical Engineering Faculty of the Miskolc University. I earned a master's degree with honours in mechanical engineering in 1967. In the very same year I began to work for a research group at the Department of Mechanics (which was financed by the Hungarian Academy of Sciences). I had the following positions there: (a) assistant (1967-1969), (b) research fellow (1969-1985) (c) senior research fellow (1985-1992). In 1992 I left the research group and was employed full time by the Department of Mechanics till 2013 when I retired. Since then I have been working part time for the very same Department (renamed to Institute of Applied Mechanics in 2014). Positions held: (a) associate professor (1992-1999), (b) full professor (1999-2013) -- head of department between (2003-2007), (c) professor emeritus since 2013. Scientific degrees: (a) PhD from the University of Miskolc in 1976, (b) PhD from the Hungarian Academy of Sciences in 1985, (c) Dr. habil from the University of Miskolc in 1998, (d) DSc (Doctor of Science) from the Hungarian Academy of Sciences in 2006. My research interests are as follows: (a) dual variational principles in micropolar theory of elasticity (c) boundary element method in a dual formulation (d) continuum mechanics of solid bodies (e) stability and vibratory problems of heterogeneous curved beams (f) eigenvalue problems of ordinary (differential equations)[differential equation systems]. Same data for my publication activity: (a) one book in Hungarian with a co-author (b) chapters in two English text books (c) thirty-seven research papers published in foreign languages (mainly in English and partly in Russian) in various journals, (d) eleven research papers in Hungarian (e) twenty-eight conference papers in English.
