Material characterization by using non-contact ultrasonic method

Abstract

Non-destructive characterization of material is given more attention due to its advantages in cost of research, procedure of experiment, accuracy of results and time taken to undergo experiment. As compare to other non-destructive characterization method, non-contact ultrasonic method does not need physical contact with specimen, surface specimen no need special preparation, analysis of any stage of formation of specimen and non-hazardous.This study is to carry out the experiment of material characterization by using non-contact ultrasonic method. First, the grid on the specimen is identifying by plot the chart grid in 5x5 mm size grid. Next, ‘surfer’software will generate a contour map, specimenimage and wire-frame image for each specimen by using the data taken. According to the specimenimage and wire-frame image, the shape, position of the defects of specimen and the change of density of defects can be identified. The area of defects of specimen is calculated by using the mean value calculation method. The accuracy of calculation area of defects is calculated by comparing the area of defects by experimental and theoretical. The result of this study shows the accuracy of this study depend of the ratio of size of defects which is the area of defects and grid size which is the area of data be taken.
