This report presents features of ultrasonic simulation
and aspects to be considered in virtual inspection
trials. A simulation trial implementation and results are
reported, with main purpose to test different features of
the selected simulation software in creation and analysis
of a virtual detectability trial.
A series of simulations was conducted using simple test
block geometry that included notch shaped flaws with
varying depths. To make the case realistic, significant
structural noise and moderate attenuation were added to
the simulation using the material properties settings.
The simulation was run using different probe frequency
values and crystal dimensions to produce variation in the
The simulated ultrasonic inspection data was analyzed
using analysis tools of the used software. The
signal-to-noise ratios and locations of the detected
indications were characterized and detectability
dependence on the notch height was assessed. Also, study
about signal-to-noise ratios measured from the detected
indications was performed.
