Abstract

Elastic waves are often used for experimental or non-destructive testing (NDT) of fiber reinforced composites. For their application, no specific prerequisites, such as electrically conducting materials, a contrast medium, or special surrounding conditions, are required. Due to reflections at any inhomogeneity in a specimen, different kinds of material failures can be detected. Depending on the setup of the specimen and the inspection task, different testing methods can be distinguished. This chapter presents typical measurement techniques based on the propagation of guided waves.
