ANALYSIS WITH GREEN’S FUNCTION FOR IR-THERMOGRAPHY NDT OF ELECTRO-THERMAL CONCRETE

摘要：

By using of the electro-thermal property of carbon fiber reinforced concrete (CFRC), inspecting crack in it by IR-thermography can be realized. The mechanism causing the temperature difference comes down to the heat transfer problem with internal heat sources deriving from electric field. Adopting certain assumptions, this paper presents the method to obtain the approximate temperature field by using Green’s function, and gives the solution of a two-dimensional rectangular field with a flaw in it. The results tally with the experimental results, and prove its reliability.
