Schematic views of the specimen preparation protocols, specimen dimension, orientation and loading direction for the three point bend and fracture tests.

For the bend specimen, specimen is named according to the orientation of osteon in the bone specimen., the long axis is parallel to osteon direction in LB, whereas the long axis is transvers to osteon direction in TB. For the single edge notch bend specimen, the 1st letter in the specimen designation refers to the normal direction to the crack plane, while the 2nd letter refers to the expected direction for crack propagation.
