Orientation-dependent plastic deformability in micropillar compression of oxide ceramics
October 2 – 7, 2022
Micromechanical testing, such as nanoindentation and micropillar compression, can be the promising tool for characterizing the plastic deformability of ceramics even at temperatures below macroscopic ductile-to-brittle transitions [1,2]. Such plasticity is possibly achieved by the fracture strength increase at small scales. The fracture strength, C , is conventionally determined as a function of a crack dimension:
