The Mechanics Colloquium is one of the historic colloquiums of MISANU. Its formal and fundamental role in the organisational structure of the Institute evolved and changed during the past eight decades, along with the changes of the Institute itself. One of its most prominent lasting achievements and its most important public activity has been the organisation of the research talks on mechanics.

The Mechanics Colloquium has earned its reputation as one of the most prestigious regular scientific meetings in the broad fields of Mechanics, with the longest continuous tradition nationwide. From the establishment of MISANU in 1946, there has always been an important group of researchers in the field of Mechanics, whose first leader was the founder and the first director of MISANU, Academician Anton Bilimović (1879-1970).

Up to 1961, the seminar talks in the field of the Mechanics, including Theoretical Mechanics, Dynamics of Fluids, Stability of Motion, and Astronomy, were part of the Mathematics Colloquium. According to Academician Konstantin Voronjec, Head of the Mechanics Colloquium in 1971, at the time of 25th anniversary of the Institute, more than one hundred such talks were held. The Mechanics Colloquium was founded in 1961. Until June 2021, there were 1392 meetings. On average, there are 24 meetings with about four foreign speakers organised annually.

The Mechanics Colloquium meets weekly, on Wednesdays at 6 pm, thus keeping the tradition from the earliest days of its founding.

The main tasks of the Mechanics Colloquium include:

• Organisation of weekly lectures, which range from expository lectures in pure and applied mechanics to original research reports,
• Organisation of public presentation and evaluation of scientific projects supported by the Ministry of Science,
• Support and organisation of visits of foreign scientists,
• Organisation and support of workshops, mini conferences, presentations of books, software, video lectures etc,
• Monitoring seminars and other research activities in the field of mechanics within the Institute.

Currently, Head of the Mechanics Colloquium is Dr Božidar Jovanović, and Marijana Babić is the Secretary of the Colloquium.

Throughout the period 1961-1965 the Mechanics Colloquium was headed by academician Tatomir P. Anđelić (1903-1993) and Prof. Danilo Rašković (1910-1985). From 1965 to 1973, Head of the Mechanics Colloquium was Academician Konstantin Voronjec (1902-1974); from 1973 to 1984, Prof. Vlatko Brčić (1919-2000); from 1984 to 2000, Prof. Veljko Vujičić (1929-2020); from 2000 to 2006, Academician Vladan Đorđević; from 2006 to 2010, Academician Teodor Atanacković; from 2010 to 2012, Prof. Katica Stevanović Hedrih; and from 2012 to 2016, Prof. Vladimir Dragović.

In the period from 1975 to 1994, the Secretary of the Mechanics Colloquium was Dr Dragi Radojević, (1947-2015). From 1994 until 2010, the secretaries were Dr Borislav Gajić, Dr Božidar Jovanović, and Dr Milena Radnović; from 2010 to 2012, Dr Srdjan Jović, from 2012 to 2017 Dr Katarina Kukić, and from 2017 to 2021, Dr Tatjana Jakšić Krüger.
