Abstract

A dual-function for differential-thermographic devices is discussed. It is shown that differential thermographic cameras can be used for rapid inspection of structures as well as for stress analysis. Reviews of forced diffusion thermography (FDT), thermoelastic stress analysis (TSA), and differential thermographic cameras are offered. A new stress intensity measurement technique using TSA data in the vicinity of cracks is described in more detail.
