Contact and Structure Mechanics Laboratory - LaMCoS

A joint research unit UMR5259 of the INSA de Lyon and the CNRS, the role of LaMCoS is to carry out research on understanding and controlling the behavior of mechanical structures and systems by studying their interfaces.

We innovate to improve understanding of fundamental phenomena to anticipate major societal challenges and respond to technological problems in the fields of Transport, Energy, Health, Biomedicine, Sport and Machine Tools.
