Coverage map of tapered CFRP component B-Scan
Model Description
This 2D model simulates an immersion B-Scan inspection of a tapered CFRP component.
The model comprises of a CFRP taper with 25 ply layers at the thick section and contains 16 ply drops to generate a taper angle of approximately 30°. A focused immersion inspection is simulated with the focus at the center of the component thickness.
The simulated model area is reduced and the transducer is approximated with a smaller stand off distance to allow for efficient simulations to be performed.
