Abstract: Phased array ultrasonic testing method is of flexible, reliable, efficient and suitable for industrial nondestructive testing. Near-field length was investigated for phased array ultrasonic testing homogeneous isotropic work pieces using oblique incident pulse shear wave. The theoretical calculations of near-field length and the simulations of the acoustic field for various deflection angles in phased array ultrasound inspections were carried out. It is shown that the near-field length decrease with increasing deflection angles when using general plexi-glass wedge of inclination angle being 36.2°. The conclusions of this paper can provide some reference for designing the testing procedure.
