Determination of the Probability of Defect Detection in Ultrasonic Testing with Straight Beam Probe
Abstract
We discuss the methodology of plotting curve of the probability of defect detection in the case of testing bulk defects in the base metal of aluminum parts. Method of control, interfering factors, finite element model for pulse-echo simulation, method of interfering factor simulation, mathematical apparatus for plotting the curve of the probability of defect detection are described. The results of simulation of 350 different defects are analyzed and curve of the probability of their detection is plotted.
