The Energetics and Theoretical and Applied Mechanics Laboratory (LEMTA) focuses its research on themes related to mechanics and energy, rational energy use, flow control, the thermomechanical behaviour of materials and biomechanics.LEMTA (UMR 7563) is a joint research unit of the University of Lorraine and CNRS. It is part of the Jacques Villermaux Research Federation for Mechanics, Energy, Processes (FR 2863). It is a host laboratory for the Energy, Mechanics, Materials doctoral school (EMMA). In Saint-Dié-des-Vosges, where it works with the European Centre for Prototyping and Rapid Tooling (CIRTES) and in conjunction with LEMTA, the Mechanics and Plastics Research Team (ERMEP) focuses on modelling the behaviour of shaping tools.
