Abstract:
In this thesis the thermal behaviour under elastic plastic stress of the stainless steel X2CrNi19-11 and oxygen free copper with Lock-In thermography was examined. The focus was the acquisition of the thermoelastic effect and dissipative temperature changes as well as their separation with thermographic methods in particular the Lock-In thermography. Therefore, a Lock-In method based on a discrete Fourier analysis was developed and used for the analysis of the thermal behavior. Influences caus...    »
