NASA/TM-108493, Russell, S.S. and Lansing*, M.D. and Horton*, C.M. and Gnacek*, W.J., Probability of Detection of Defects in Coatings With Electronic Shearography, Materials and Processes Laboratory, Science and Engineering Directorate NASA Marshall Space Flight Center, AL 35812, *University of Alabama in Huntsville, Huntsville, AL, June 1995, pp. 18, Format(s): PDF 793k |
The goal of this research was to utilize statistical methods to evaluate the probability of detection (POD) of defects in coatings using electronic shearography. The coating system
utilized in the POD studies was to be the paint system currently utilized on the external casings of the NASA space transportation system reusable solid rocket motor boosters.
The population of samples was to be large enough to determine the minimum defect size for 90-percent POD of 95-percent confidence POD on these coatings. Also, the best methods to excite coatings on aerospace components to induce deformations for measurement by electronic shearography were to be determined.
