Abstract :
Ultrasonic Phased Arrays are an emerging technology in nondestructive testing and evaluation. The type of linear phased array probe is a prevailing type in which elements are placed side by side and longitudinally. In this paper ultrasonic phased array testing (UPAT) is introduce and in order to modeling and design UPAT consideration of wave equation solution by Finite Element is proposed. ABAQUS 6.14 is used as finite element software. Wave propagation in two form is simulated, straight and inclined. Direct and sectorial scanning is based on these forms of waves propagation. Time delay is the most important issue that should be considered in UPAT modeling. Results of simulation is verified by comparing previous research in UT field. Finally, results in additional to proposed the obvious view of UPAT, it's so useful for properly design probes and defect detection UPAT devices. Using finite element methods in this field is cost and time effective.
