NDT techniques based on the ultrasonic phased array technology are applied in various industrial contexts. For the reliable application of phased array techniques, it is essential to have well knowledge on the characteristics of radiated beam profile from array transducer and ultrasonic wave propagation in test materials. This paper proposes a mathematical model of the phased array transducer and a simulation tool to estimate transmitted waves from the transducer and scattered waves from flaws. The simulation tool is based on the BEM, and a pulse shaped wave is used in this analysis for the transient wave propagation. Here wave fields are visualized to understand the feature of scattered wave forms measured at the array transducer.
