Figure 1

Snapshots at time t = 38 s show the spatial strain and temperature fields. (a) An example of an IR image, superimposed on the background. This temperature field shows the hot spot which has a temperature 0.4 °C higher than the background value of 22.0 °C. The coordinates are indicated, and one may see how the paper sample texture has been enriched for easier DIC computations. (b) DIC (εyy) and IR fields at the same instance in time. (c) DIC and IR profiles parallel to the crack propagation direction at two instances of time.
