Calibration facility for infrared thermography systems at PTB (2001)

Hartmann, Jürgen ; Gutschwager, B. ; Fischer, J.

Section 2 of the present paper introduces the two calibration facilities, presents the applied blackbody radiation sources with the achievable uncertainties, the collimator optics, and the climate box. A short introduction of the experimental techniques used and presentation of some experimental results for different camera systems follows in Section 3. A final conclusion is given in Section 4.

DFG Research Group 537: Modelling reinforcement corrosion – Numerical modelling of bond strength of corroded reinforcement (2008)

Fischer, Christian ; Gehlen, J. ; Ožbolt, C.

The calculations were performed with four different specimen types (see Table 1). Each type was calculated without expansion (reference calculation) as well as with five different expansion values. The expansion was simulated before the application of the pull-out load.
