Disciplinary research at Institut Polytechnique de Paris is based on the expertise of its founding schools. Mechanics and Energetics is one of ten disciplinary research fields bringing together top researchers and PhD students at state-of-the art laboratories and facilities. Mechanics focuses on the study of materials and environments, whether solid, fluid, porous, inert, active or living, as well as the structures and systems made from them. At both a very small and very large scale, it studies their movement, deformation, state of equilibrium and transient response when subjected to mechanical loads as well as when combined with thermal, electromagnetic, chemical, biological or other effects. Research at the Institut Polytechnique de Paris focuses on both solid and fluid mechanics and on energy and environment-related issues. It covers a wide range of applications, including meteorology, civil and mechanical engineering, transportation, energy, defense, living organisms and the design and characterization of innovative materials and structures for an array of industries.
