The International Society for the Interaction of Mechanics and Mathematics (ISIMM) is an association of professional mathematicians and mechanicians dedicated to promoting the beneficial influence of each of these disciplines on the other.

ISIMM organizes regular meetings and launches publications both as proceedings and as separate textbooks or monographs.

Historically, there had been a planning period before that time which had culminated in a meeting in Lecce, Apulia, Italy two years earlier.

Hence the idea of ISIMM came naturally, a society with an impressive constitution and with the backing of a truly international group of scientists from all over the world, even though the European element was predominant.

Since 2022, ISIMM is legally a non-profit organization anchored under German law as "e.V" (i.e. ‘eingetragener Verein’) registered at a responsible court in Wurzburg.
