Experimental Validation and Application of a Phased Array Ultrasonic Testing Model on Sound Field Optimization

In safety dominant industries, nondestructive evaluation (NDE) is crucial in quality assurance and assessment. Phased array ultrasonic testing (PAUT) as one of the NDE methods more promising compared with conventional (UT) method terms inspection speed flexibility. To incorporate PAUT, techniques should be qualified, which traditionally performed by extensive physical experiments. However, development numerical models simulating UT method, it expected to complement or partly replace experiments intention reduce costs operational uncertainties. The validated ensure its consistency reality. This validation work can done comparing model other corresponding purpose current focuses on experimental a model, simSUNDT, developed Chalmers University Technology. Validation conducted different data presentations (A-, B- C-scan) from simulated results some well-defined artificial defects. Satisfactory correlations observed comparisons. After validation, sound field optimization aiming at retrieving maximized echo amplitude certain defect started using model. also reveals flexibility parametric studies simulation models.
