TY - JOUR A1 - Maierhofer, Christiane A1 - Wiggenhauser, Herbert A1 - Brink, Arne A1 - Röllig, Mathias T1 - Quantitative numerical analysis of transient IR-experiments on buildings N2 - Impulse-thermography has been established as a fast and reliable tool in many areas of non-destructive testing. In recent years several investigations have been done to apply active thermography to civil engineering. For quantitative investigations in this area of application, finite difference calculations have been performed for systematic studies on the influence of environmental conditions, heating power and time, defect depth and size and thermal properties of the bulk material (concrete). The comparison of simulated and experimental data enables the quantitative analysis of defects.
