The Mechanics of Vibrothermography
Abstract Vibrothermography is a term coined by the authors to describe a concept and related techniques whereby the internal integrity and uniformity of materials and components is interrogated by observing the heat pattern produced by the energy dissipation which occurs when a specific vibratory excitation is applied to the test piece. In particular, “vibrothermography” consists of the study of thermographic (heat) patterns which are recorded or observed in real time during such an excitation. It has been observed that the details of the mechanisms which produce such dissipative heat are directly related to the mechanisms of material deformation and degradation in several important ways, a fact that provides the basis for the use of this scheme as a nondestructive test and evaluation method and general philosophy. The present paper is an overview of this field which begins with a tutorial explanation of the basic foundations of the method, continues with a development of the manner in which the information provided by the method is related to the mechanics of the response of the test specimens — to the extent that it is understood — and closes with a survey of results and applications of the method.
