Structures and Systems Integrity (ISS)
The research carried out within the Structures and Systems Integrity (ISS) research axis focuses on structures and systems in their conditions of use and failure. The studies concern in particular the nonlinear dynamic response of slender structures and complex systems (rotors for example), as well as the response of structures to accidental overloads (e.g. impact), including large deformations and deformation rates. To carry out this work, numerical methods and methodologies for highly nonlinear structures, materially and geometrically, are developed.
