Introduction In recent decades, the development of depth sensing indentation equipment has permitted the easy and reliable determination of two of the most conventional mechanical properties of materials: the hardness and the Young’s modulus.
The mechanical properties of the material are presented in Table 2.
The material is considered isotropic, with isotropic work-hardening and described by the Swift law ( n 0)(K �+�=� ) where K, 0� and n are constants for each material.

Raw material The material used is the calcined kaolin which is crushed by Leimeng mill.
First, putting the powder in the hopper, then let the materials fall down and collect the materials in the container and weight it.
The weight of the materials is W1.The whole materials weight is W0.

Among them, the development of digital technology to the positive role in promoting the construction of digital library information resources, speed up the digital library information resources, improving the utilization rate of books and materials.
The Internet has a lot of digital information resources retrieval can be free, in China journal full text, Chinese scientific journal database (VIP), Wanfang digital periodical, superstar digital library, as well as EBSCO, Elsevier, Springer and other database, in addition to the conference papers, journal articles, patents, standards and other documents, and all kinds of network periodicals, newspapers, computing technology can from the vast amounts of information quickly choose to meet those disciplines demand database using the clouds, to meet the needs of practical application of the user better.
According to the State Press and Publication Administration statistics, domestic four retrieval of CNKI, Wanfang Data, VIP information and Longyuan and periodicals net has been basically covers more than ninety percent domestic journals, seemingly convenient for users, but the four big search included the journal has a considerable number of duplication of resources.

In the fracture mechanics, material fatigue is the process of the initial micro-cracks under the load extended to the destruction.
Where c is the crack length; N is the number of load; is the stress intensity factor increase, and is the material constant, respectively, in the paper for 3.5 and 3.
