facet fracture

SURFACE MELTING Method for determining crystal orientation of fracture facet using electron back-scattering diffraction

确定断裂表面晶体学取向的电子背散射衍射方法

Methods Part of elements under the posterior articulation were removed from a normal finite element model of calcaneus and talus to simulate malformation of compression of the posterior facet after fracture of calcaneus.

方法在跟骨有限元模型上切割部分后关节面，模拟跟骨骨折后的后关节面压缩畸形。

The dual-plane observations of fracture surface and adjacent side surface microstructures show that annealing twin boundary fracture, intergranular and transgranular cracking result in smooth planar facet, smoothly curved facet and rough facet, respectively.

对断面与侧面组织的双面观察表明，退火孪晶界断裂、沿晶断裂和穿晶断裂分别形成光滑平面状断裂刻面、光滑曲面状断裂刻面和粗糙不平的断裂刻面。
