The crack of mode I spread always occurred in brittle materials and it is the most dangerous, so crack mode I is always taken account.
Griffith declared that the fracture is due to the spreading of crack when he studied the fracture of brittle materials like glass and ceramics.
Obviously when stress σ is up to σF, the crack will propagate to result to brittle fracture, and there is so called Griffith's criterion of brittle fracture of materials.
In addition there is a large temperature grad under the working conditions, and its have effect on the parameters of materials and the boundary exertion.

The material model was approximately described by a bilinear stress-strain curve.
The initial slope of the curve was taken as the elastic modulus (E) of the material which was 2.06105MPa.

Because the distance between two plastic hinges and thickness of the angle steel have the same magnitude order, we have to take the influence of bending shear upon the material yield into account.

Biosensor materials.
The charge transfer from the bio-molecule analytes contact to the nano-materials is the sensing mechanism.
The nano-materials showed a fast improvement for mobile and digital health-care applications for physicians and patients.

Model of framework is out of relation with load but is determined by trait itself and material, so disk spring only was restrict without load.
