Title: Determination of delamination depth in concrete structure based on inverse analysis of thermography data
Abstract: Infrared thermography method is an effective technique for NDT of concrete structure. This paper describes the determination of delamination depths in concrete structure using passive infrared thermography. The sequential thermography data on the surface of concrete specimen are measured by infrared thermography with microbolometer detector, and the solar energy is measured by pyrheliometer in all day. FEM analyses are carried out to calculate the transient temperature on the concrete under the given weather and solar radiation conditions. Based on the results of inverse analysis, in which computed temperature data were compared with experimental data, delamination depth was quantitatively determined.
