SIMULIA Customer Conference 2011 in Barcelona (May 17-19)

Critical Materials will present a paper entitled "Vibration-based Structural Health Monitoring of composite structures", at the Simulia Customer Conference that will be held in Barcelona. In this work, the feasibility of a vibration based damage identification method in composite structures is explored through FE-Finite Element simulations, in the frequency domain, performed with the use of Abaqus FE package.
Vibration-based Structural Health Monitoring (SHM) is a method to assess damage in structures, working in the principle that variations on the stiffness (such as delamination), mass or energy dissipation properties of the structure will alter its dynamic response (e.g., mode shapes and natural frequencies).
Composite laminate and sandwich structures are more often used in aircraft components. Composite damage features peculiar mechanisms, the most relevant being layer delamination in laminates, skin debounding in sandwich constructions and composite penetration. Delamination and debounding may be internal to the structure and not visible externally render difficult their assessment.
Critical Materials focused its attention on the monitoring of the dynamic behavior of structures, nominally, the changes in the dynamic response of healthy and composite structures subjected to several damage scenarios.
