A Dynamic Data-Driven Framework for Damage Predictions in Materials & Structures
Monitoring real-time failure in fiber-reinforced composites using nondestructive evaluation (NDE) is a fairly difficult task due to the associated evolving material state uncertainties, as well as due to data management mining and signal processing challenges. In this context, a number of statistica...
