Introduction
The capability to synthesize diamond thin films using chemical vapor deposition enables the
exploitation of the many unique material properties of bulk diamonds.
Diamond is an ideal material for an emitter, because it has a very low electron affinity, resulting in very low energy requirement to drive a visual display unit (VDU).

He actually tried to measure fracture toughness of structural steels when he noticed crack blunting due to plastic deformation at the crack tip, named Crack Tip Opening Displacement (CTOD) which was proportional to the loading, thus representing the CDF, whereas its critical value (CTODc) represents material property.
As a final step, non-dimensional variables Sr = s/sc and Kr = KI/KIc are defined, where it is supposed that Keff equals to the fracture toughness of the material, so that Eq. (2) becomes: (3) If the material is completely ductile, the structure fails due to plastic collapse at Sr = 1, while for fracture of a completely brittle material Kr = 1.
