dc.description.abstract | Development of ultrasonic non-destructive testing (NDT) techniques has involved a combination of both simulation and experimental methods. This paper describes a numerical simulation and imaging technique, which incorporates direct, mixed and specular reflections from the internal defects. The NDT simulation algorithm is based on an extended diffraction model of the ultrasonic transducer. The B-scan image correction method has been developed taking into account the angle of the transducer wedge and specular reflections. The most typical defect orientation cases were analysed. An aluminium test sample with side drilled holes was analysed using computer based simulation and experimentally. The comparison of the results has shown good correspondence. A simulation of V-weld inspection was also carried out. | eng |
