Intrinsic Amplitude Distributions and the Ultrasonic Inspection of Fiber-Metal Laminates

  • Martin P. Jones

Abstract

For any nondestructive inspection, there are many factors that influence the probability of detection of discontinuites.1 The work described in this paper mainly examines the effect of amplitude variations, intrinsic to a material,2 on the probability of detection of isolated discontinuities. Although the present approach could be adapted to any material, many discontinuity types, and several methods of nondestructive inspection, the application described here is on fiber-metal laminates and the ultrasonic detection of delaminations.
