During the 1960's, a strong group of scientists-theoreticians in the field of mechanics (oscillation theory, continual medium mechanics) formed in the Riga Polytechnical Institute under the guidance of academicians Y. Panovko and E. Lavendelis. The practical implementation of the scientific ideas became actual, therefore a laboratory of an according profile was created. Lot of the current professors (Janis Viba, Bruno Grasmanis, Igors Tipans etc.) in Mechanics field of the Riga Technical University have worked in this laboratory, many of the highly-qualified former staff of this laboratory now successfully work in many different countries of the world. Along with the restoration of Latvian independence the structure of the laboratory has went through some change, namely, the experimental base has been reduced - however, computerization and the number of developments in the field of modern information technologies have increased. Computers have always played an important part in the work of the laboratory's scientists. The chief pioneer of computerization has been the brilliant scientist and fighter for the Latvian national independence Dr. Vilnis Eglais, whose ideas, algorithms and works in the field of optimization are used and quoted by scientists of many countries of the world up to this day. V. Eglais is considered to be the first scientist who formulated the task of the computer experiment planning, and was the first scientist in the world who, in 1976, proposed the experiment planning method that is now known as the Latin hypercube method. The doctors of engineering sciences Peteris Auzins, Vladlen Putyatin, Peteris Sliede, Guntis Svikis, Janis Zviedris, as well as many other talented scientists have all significantly contributed to the development of the laboratory. In 2019 Scientific lab of RTU Nonlinear effects in ocillation systems (Prof. S.Tsifansky) was added to MMD SC.
