However, these were not applied to “realistic” defects and required a significant investment of scan time. Phased array ultrasonic technology has been su gested as an alternative method that would improve not only sensitivity but also throughput3! as it would allow fast scanning over a large region with hi h Signal-to-Noise Ratio (SNR) for defect depth discrimination and would likely be cost effective . f? APPROACH To evaluate the detectability of these seeded representative defects by conventional ultrasonic methods each of the three tiles was scanned first using Argonne’s water-coupled SONIX ultrasonic system.
This paper will present the test specimens that have been used so far in these studies, the details of the data acquisition parameters and the results obtained to date. INTRODUCTION Poor ballistic performance of SIC armor tile for vehicles is a concern for reliable protection of military personnel. An effective non-destructive screening technique to sort “good” tile from “bad” tile, assuming such knowledge exists, would be one possible method to reduce ballistic performance failures’. One likely source of this differentiation would be the presence of flaws, such as inclusions of differing density or large-grain regions’.
48 . Advances in Ceramic Armor II Spherical Indentation of Sic Indenter size and damage as a function of force is shown in Fig. 6 for Sic-N. 27, 36. 58, 80. and 1 1 1 N forces, if only elasticity were present. 3. 3. 2. 4 GPa, respectively. Obviously the elastic limit was exceeded at all these forces so the authors fully realize that those reported average contact stresses are inaccurate; however. it is convenient for the sake of discussion to report those values nonetheless. The 13N force shows the disadvantage of the use ofthe 300 pm diameter indenter to identify yield: the average contact stress was already above 15 GPa.
