Typical Compression-to-Failure in Situ Compression Test of Individual Nanocrystalline Hollow CdS Sphere Obtained Using Hysitron's TEM Picoindenter - PI 95
This video was recorded during a typical compression-to-failure in situ compression
test of an individual nanocrystalline hollow CdS sphere and the corresponding
load and displacement data. The experiment was run in displacement control.
Through synchronizing the microstructure evolution and the mechanical data with
time, it was found that the fracture pressure of the particle is about 1GPa.
Considering that the Young's modulus of CdS is only about 42GPa, the value
is surprising large. (Shan
