Summary[edit]

Description
English: Supplementary Movie 1 In-situ TEM nanoscale CTOD measurements of conch shell. The results of two separate tests are displayed in series. The TEM movies were recorded at 25 fps and played at 37.5 fps (1.5 times faster playback speed) for the first movie (Conch A, analyzed and presented as part of Fig. 2) and at 25 fps for the second movie (Conch B). The mechanical testing was conducted at a constant displacement (3 nm/s) of the FIB-machined diamond indenter normal to the TBs. After being initiated at the notch, the crack exhibits several branching and deflection as it propagates across the nanoscale twins. The plot of CTOD versus crack extension is displayed in sync with the corresponding movie. After playback of each TEM movie, the TEM images taken after the test are shown to highlight the crack propagation path.
