SYMPOSIUMS ON NONLINEAR MECHANICS IN YUGOSLAVIA

This symposium entitled "Nonlinear Sciences at the Threshold of the Third Millenium" was organized with a wish to unite in a single symposium, on the basis of the mathematical phenomenology of Mihajlo Petrović Alas, quite disparate sciences with the aim of integrating the knowledge of the participants of our symposium. This is a serious and a long-term task of science.
How did it all start? It started here, at the Faculty of Mechanical Engineering, Univer-sity of Niš.
Prof. Danilo P. Rašković (Ph.D. in mechanical engineering and BS in mathematics), the first head of the Chair for Mechanics and Automatics, while teaching mechanics at the Department for Mechanical Engineering at the newly founded Faculty of Technical sciences, directed his youngest and most talented students towards studying nonlinear oscillations and nonlinear mechanics. Thereafter, he initiated a cooperation with the academician Jury Aleksejevitch Mitropolsky and a leading school of nonlinear mechanics, asymptotic methods and nonlinear oscillations at the Institute for Mathematics in Kiev. That is how a center for nonlinear mechanics was established at the Chair for Mechanics, Faculty of Mechanical Engineering in Niš. They were supported by the Institute for Mathematics – SANU from Belgrade and by the scientist from all the Universities in Yugoslavia, especially Universities in Belgrade and Novi Sad. The organization of symposiums on nonlinear sciences followed.
The first symposium on nonlinear mechanics - Nonlinear Dynamics, organized by JDM and Serbian Society for Mechanics, was held in Arandjelovac, 23-25 November 1983. Prof. Jury Aleksejevitch Mitropolsky gave the invited plenary lecture. All the members of the Chair for Mechanics and the Chair for Hydraulic Engineering of the Faculty of Mechanical Engineering University of Nish took part in this and other symposiums; they were coorganizers as well.
The Second Yugoslav Symposium on Nonlinear Mechanics entitled: "The First Yugo-slav Conference on Nonlinear Deterministic and Stochastic Processes in Dynamical Systems with Applications YCNP Niš '91", August 27-30,1991, organized by the Faculty of Mechanical Engineering was held in Niš. The Chairman of the Scientific Committee was Prof. Veljko Vujičić, while the Chairman of the Organizing Committee was Prof. Katica Hedrih. Proceedings of Abstracts was printed; the papers and invited lectures which were approved were printed in the first and the following issues of the University Journal – Facta Universitatis, new Series – Mechanics, Automatic Control and Ro-botics. This Series was the third Series, which was being published, besides the Series Mathematics, Informatics and Electronics, and Energetics. William Nash, Kazuyuki Yagasaki..., gave the invited lectures, at this international symposium.
The invited plenary lectures were given by the following Yugoslav scientists: Veljko A. Vujičić, Vladan Djordjević, Ljubomir Grujić, Božidar Vujanović, Livija Cvetićanin,...
Prof. Slobododan Laković, the Dean of the Faculty of Mechanical Engineering University of Niš and a member of the Organizing Committee, has significantly contributed to the success of this symposium.
The Third Yugoslav Symposium on Nonlinear Mechanics was held in the form of a Minisymposium, as a part of the XXII Yugoslav Conference on Mechanics in Niš in 1995. The Faculty of Mechanical Engineering in Niš, with co-organization by the Faculty of Civil Engineering organized this Congress as well.
The Chairman of the Organizing Committee was Prof. Katica (Stevanović) Hedrih; Prof. Zoran Boričić, the Dean of the Faculty of Mechanical Engineering, was very hospitable. Academician Vladan Djordjević, the President of JDM has contributed to the successful organization of this Congress and the Minisymposium. The Chairman of the Scientific Committee was Prof. Veljko Vujičić. Professors Yu. A. Mitropolskiy, V.V. Rumyantsev, Felix Chernousko, Anatoliy Martinyuk, Valentina Filchakova, Dan Sta-matiu,... were guest at this symposium.
The Fourth Symposium on Nonlinear Mechanics was held in 1997, again in the form of a Minisymposium, as a part of the XIII Yugoslav Congress on Theoretical and Applied Mechanics. This Congress, held in the Congress Center – Zvezda in Vrnjačka Banja, was organized by the Yugoslav Society for Mechanics. The organization of this Symposium was helped by the Institute for Mathematics – SANU and the Faculty of Me-chanical Engineering in Belgrade.
The Chairman of the Scientific Committee was the academician Nikola Hajdin, and the Chairman of the Organizing Committee was Prof. Katica Hedrih. Professors Anthony Kounadis, Ilia Blekhman, Guiseppe Rega, Angel Baltov,... were guest at this symposium.
The Fifth Symposium on Nonlinear Mechanics was being organized with the wish for it to become a tradition and to gather the connesseurs of nonlinear phenomenology from disparate sciences and dynamic systems and for it to become renown all over the world.
The year of the Fifth Symposium was the year of the 10 th Jubilante issue of the Uni-versity Journal – Facta Universitatis, new Series – Mechanics, Automatic Control and Robotics. Let these symposiums and the journal Facta Universitatis become a permanent characteristic of the University of Niš, Faculty of Mechanical Engineering in Niš and scientific achievements of the Yugoslav scientists; let the matter of participation at these symposiums become a metter of prestige for scientists from other countries too.
This symposium was contributed to Yugoslav science, which has been disrupted by Nato intervention, and let it be a sign that we are better than those who preempt the achievements of others; we don't buy the we create them by our own spiritual effort and creativity in order to use the for the well-being of human kind.
