Abstract
The paper considers one of the urgent and difficult to implement problems dealing with flaw detection. This is a timely diagnosis of various damages in hard-to-reach places of metal structures. The greatest difficulty arises with the detection of internal defects due to the fact that they are located inside metal structures and are not available for visual inspection. One of the solutions to this problem is the application of the ultrasonic testing method using electromagnetic acoustic transducers (EMATs) on a phased array. The control of the input angle and focusing into the selected zone of the ultrasonic wave, due to which irradiation occurs at different angles to the discontinuity, are the main advantages of the proposed method of non-contact flaw detection of metal structures. In this case, the registration of the reflected wave and its processing provides the most reliable information about the shape and size of the defect. A mathematical model for calculating the acoustic field of the 32-element EMAT shear vertical wave phased array was developed. A computer simulation of the process of reflection of the ultrasonic beam with different sizes and located at different angles was carried out. The influence of the size and location of defects in the plate on the formation of the reflected signal was investigated. The simulation results show that as the defect size increases, the amplitude of the wave reflected from the defect increases linearly. This allows us to develop a sensor design for recording the reflected wave with minimal dimensions.
