Part of the Fracture Mechanics of Ceramics book series (FMOC, volume 1)


Numerous nondestructive inspection techniques are available today for the detection of flaws in a variety of materials including ceramics. The purpose of this paper is to present an overview of current NDT principles and techniques including criteria for the proper selection of effective test methods. The process of selecting and developing suitable test procedures for a particular quality assurance purpose is governed by several factors. One is the nature of the flaws anticipated, another the characteristics of materials and structures involved, and a third the location and configuration of defects.

In discussing the various options available to the designer or user of nondestructive test procedures, one must first attempt to clarify the scientific as well as the semantic problem which has arisen from the rapid proliferation of inspection techniques. The complexity of the subject can be reduced by establishing three major categories of test disciplines under which all currently known NDT methods can be classified. They are:
  • Motion-of-Matter Testing

  • Electromagnetic Testing

  • Probing Media Testing

Using this grouping, individual NDT techniques are discussed with primary emphasis being placed on the general principles and on recent innovations and improvements of the technique.
