Fracture energy of 6H-SiC at the microscale: effects of testing geometry and notch preparation
Zhuoqi Lucas Li, Siyang Wang, Ao Li +5
Micromechanical testing enables small-scale fracture energy measurements, but values depend strongly on geometry and specimen preparation. Here, the fracture energy of the single-c…

Observing the crack tip behaviour at the nanoscale during fracture of ceramics
Oriol Gavalda-Diaz, Max Emmanuel, Katharina Marquardt +2
Ultimately, brittle fracture involves breaking atomic bonds. However, we still lack a clear picture of what happens in the highly deformed region around a moving crack tip. Consequ…
