Editor's Notes
The Answer is: A whole bunch of very different things. X-Ray, Ultra Sonic Transmission, Vibro Thermography, Fluorescent Penetrant, Eddie Current, Computed Tomography (CT)
The Data has to having some element that makes it possible to integrate it. That Element is the the actual physical specimen. Part of what we are doing is adding spatial awareness to all the. The great thing about this diverse data is that we can know a lot about an object. And what we really want to do is make a Digital Twin!
Nope, not quite. A Digital would be a model of an actual part, or machine. Right now we have a lot of models of things, CAD Models, FEA models but those are usually models of an idealize generic part. Anyone who actually makes things know there is a difference between what you planned to make and what you actually make. The Digital twin uses that original model of what you intended to make and NDE data to give a better representation of an actual part in use.
Example: I have an wind turbine in service….
So what is the problem…. Uncertainty!!
Because it exists! We get things wrong, we perceive things incorrectly, and measurements are faulty
We Use Bayesian Methods to track the best estimate and the uncertainty as time goes by and new inspection data becomes available
