Chairman:



Prof. Dr. Vlatko Brcic (1919-2000)

Abstract

• Vlatko Brcic, PhD, graduate civil engineer and graduate mathematician, retired full professor, deceased on August 22nd, 2000, in Belgrade. Professor Brcic was born on September 16th 1919 in Varazdin, where he finished the elementary and grammar school. He enrolled at the Faculty of Philosophy in Zagreb, at the Department for Theoretical Mathematics, and graduated in June 1942. Having finished his mathe-matical studies, he en-rolled at the Faculty of Civil Engi-neering in Prague, and graduated in 1947. Professor Brcic started engineering practice as a statics engineer, and in March 1948 he was transferred to the building area of New Belgrade. At that time he lectured in popular courses on civil engineering to the young people helping to build New Belgrade. This can be pronounced to be the beginning of his long pedagogical work. After that, in October 1951, he went to the Faculty of Civil Engineering in Belgrade, where he was elected full lecturing assis-tant for the subject Mechanics.

academician Tatomir P. Andjelic (1903-1993)

Abstract

• Dr Tatomir P. Andelic, professor of the Faculty of Natural Sciences and Mathematics, University of Belgrade, full member of the Serbian Academy of Sciences and Arts and International Astronautical Academy in Paris. T. P. Andelic studied mathematics, physics and astronomy which lead to his formation as theoretician of mechanics. He published over 70 works, among which are 9 university textbooks. He addressed the problems of rational mechanics, Riemann geometry, numerical methods in mathematics, and also historical and philosophical problems of mechanics. He is very active in scientific societies, especially in disseminating scientific knowledge. T. P. Andelic was a Dean of the Faculty of Natural Sciences and Mathematics, and now is a Director of Mathematical Institute of the SR of Serbia. He is decorated with the Order of Labor With Red Flag and Order for Merits With Gold Star.

Prof. dr dipl. Math. Danilo P. Raskovic (1910-1985)

Abstract

• Danilo Raskovic, a doctor of technical sciences, mechanical engineer and mathematician with a university degree, started the first scicntifically based courscs of mechanics at thc Faculty of Mechanical Engineering in Belgrade. He also introduced courses on the subject of strength of materials, elasticity theory, and oscillation theory all of which he taught, too. He authored many textbooks of high scientific standard and large circulation. He introduced vector, matrix and tensor calculus in thc studies of mechanics at the Faculty of Mechanical Engineering in Belgrade and, later on, did the same at the Mechanical Engineering Faculties in Nis, Kragujevac and Mostar. He enabled the Faculty in Belgrade, and similar schools elsewhere, to produce highly qualified and educated engineers which was one his greatest contributions. He wrote the first university textbook in Serbia on oscillation theory prescnting his original research results. He achieved considerable scientific success in the fields of elasticity theory and oscillation theory. With a good human resource base at Nis Faculty, which he had set up, Raskovic started research work into the field of nonlinear mechanics.

Chairman:



academician Konstantin Voronjec(1902-1974)

Abstract

• Konstantin Petrovic Voronjec was born on January 30, 1902, in Kiev, in a family of well-known Russian scientist on mechanics (dynamics of nonholonomic systems), Petar Vasiljevic Voronjec, professor of the Kiev UniZversity. After completing the elite Kiev Gymnasium, Konstantin Voron^c was mobilized by the White Army, and took part in some of the most difficult battles against members of the Red Army, during 1919-1920. After the break of White Army, together with the thousands of refugees he escaped to Belgrade, Serbia. He graduated from the Faculty of Philosophy in Belgrade, group for mathematics and physics. For a short time he taught at gymnasium in Krusevac. At the end of 1920 he returned to Belgrade and set up all his efforts to prepare his doctoral dissertation, entitled: Rolling of a solid body over an elastic support, which he defended in 1930. Members of his doctoZ ral committee were Anton Bilimovic, mentor, Milutin Milankovic and Mihajlo Petrovic. Subsequently he went to Paris, France, and took the post at the Institute for Fluid Mechanics of the French Ministry of Air Crafts. In France, under the supervision of professor Henri Villat, at the Faculty of Science of the Paris University he defended another doctoral dissertation that consisted of two parts, one of which related to stability of convective fluid flows, the other to fluid flow in thin layers over curved surfaces.
