A dielectric loss is an appearance of the fundamental properties of crystalline as well as amorphous semiconductor materials.
The origin and nature of dielectric losses in these materials has, therefore, become a matter of curiosity.

May be appropriate to reduce the use of materials, such as reducing the thickness of steel plate.
By the force the larger width of the column on the surface channel may be appropriate to increase the use of materials to increase their scale.

Crankshaft Finite Element Model.
Two main journals bears constraints from bearings, output side bears constraints in axial direction and circumferential direction.
The fatigue analysis of crankshaft is based on static analysis; the maximum stress is much lower than material yield strength, so the crankshaft fatigue problem is attributed to high cycle fatigue.
The detailed steps are: create a new project, set alternative stress as “equal stress (Von Mises)”, average stress as “Gerber” [6], considering material real S-N curve has some deviation from theoretic curve, fatigue reduction factor are determined as 0.9, set material property as QT-8000-2 fatigue S-N curve, interpolation method as “double-log”, maximum loads as “total reverse”, maximum circulating times as 107.
