Abstract

Ultrasonic testing has widely used in industry for defect evaluation. However this technique has several limitations such as fixed beam separator and mechanical scanning. These limitations can be solved by using phased array technique which used multiple element of arrangement with time delay that can be steering of focusing. A study is being carried out to study the effect of size PZT element on the excitation of phased array transducer. Several design parameters of phased array model need to be considered such as number of elements, distance between elements, frequency, and aperture size affect the excited beam of transducer. The guided wave with different modes which is symmetrical and anti-symmetrical is used as a principle to propagate wave in large structured using a single fixed point. Simulation of aluminium plate without defect for beam steering and beam focusing with time delay is being modelled using ABAQUS software. The visualization of wave propagation on defect is observed and compared with the different model.
