The idea of organizing the Polish Congress of Mechanics was born in 2005 among members of the Polish Society of Theoretical and Applied Mechanics. The first Congress has been organized in 2007. In 2013, the organization of the Polish Congress of Mechanics was included in the statutory tasks of the Polish Society of Theoretical and Applied Mechanics. Referring to the splendid tradition of Polish Theoretical and Applied Mechanics, the Congress has become one of the most important international scientific conventions representing this domain of science and gathering every 4 years about 500-600 specialists, who deal with the issues of mechanics and mechanical engineering in a broad sense. The organization of the Congress allows for the connection of many scientific communities, researchers, and engineers from various universities, faculties, research centers, and institutions. Such scientific meeting is an excellent place for presentation, discussion, and dissemination of new achievements and ideas relating to the theoretical foundations as well as practical applications of mechanics. The Congress presents the current state-of-the-art research in all disciplines of classical and quantum mechanics, solid and fluid mechanics, computational mechanics, applied mechanics, and physics, as well as structural mechanics and engineering.
