Fig. 5

This is visualized by overlaying the strain (ϵxx) on images of the notch and crack. Left to right, all images show an image of crack initiation, the image of crack initiation with the corresponding strain state overlaid, and the strain state at crack initiation overlaid on the image of the next step of crack propagation. In the 3D images the notch is colored in gray and the crack is colored in green. a–c Examples of 2D DVC results for a room temperature sample. d–f Corresponding examples of 3D DVC results for a room temperature sample. g–i Examples of 2D DVC results for a 160 °C sample. j–l Corresponding examples of 3D DVC results for a 160 °C sample.
