Vibrothermography: Investigation and Development of a New Nondestructive Evaluation Technique.

Abstract

A summary is presented of the major findings of a program whose objective was to investigate the phenomenon of preferential heat generation around damaged regions in materials subjected to mechanical vibrations and to develop an understanding of the mechanisms involved in this process. Vibrothermography is a nondestructive inspection technique based upon the utilization of this phenomenon. It has been found that this technique has much potential for inspecting composite materials. A significant amount of knowledge has been gained concerning the nature of the heat generation process and the relation of the frequency dependence of the heat patterns to the mechanical excitations.
