Thermographic NDT to estimate interfacial flaw sizes between steel plates and concrete members
This paper presents a nondestructive technique to estimate two-dimensional size and depth of interfacial flaws between concrete members and the enclosing steel plate by the infrared thermographic method. In this procedure, in order to investigate the influence of a defect in a thermography, liquid nitrogen was used to cool the surface of the steel plate. Its thermal distribution was measured. From these measurements, it was possible to estimate the diameter of circular defects from the calculated inflection points in the thermal distribution curve. The process to evaluate the depth of the flaws by using the relation between the volume of the flaws and proposed thermal parameters is also described.
