Figure 3From: Thermographic inspection of cracks in the mixed materials statue: Ratto delle Sabine The surface temperature increase at the back side of the inflow hole (mixed materials sample). The different curves indicate the increase vs time of the surface temperature at the back side. It can be observed that during the heating of 13,3 minutes the temperature increases with 3,7°C and after 3–4 min the temperature increases of about 3°C (red arrow).Back to article page
