Theme


The overarching theme of the Center research activities is an integrated approach to intelligent structural health management (ISHM) of safety-critical aerospace, mechanical and civil structures. Intelligent SHM involves feedback-based prediction of structural integrity. On-board diagnostic sensors provide continuous or on-demand information about the state of a structure, and the data from the sensors is incorporated into structural analyses and damage evolution models to assess the state of the structure, and to make probabilistic prognoses about the remaining lifetime. Intelligent SHM represents a shift away from routine inspections which are currently scheduled based on ensemble statistics, to inspections that are scheduled based on the actual state of the structural health of individual structures. This approach results in improved safety as well as in increased efficiencies in terms of cost and downtime.
