Introduction Macro-synthetic fiber (which diameter is greater than 0.1mm) is new-style strengthen-material started the end of 20th century.
Fig. 1 Details of the configurations The Mechanical Properties of Materials.
Fig.6 Equivalent viscous damp Conclusions Based on the comparison of four specimens, the following conclusions can be drawn: (1) The axial compressive strength of concrete with fibers gets slightly lower than ordinary of concrete, through the material test

Some of the materials have much good comprehensive function, they are difficultly machined because of the material’s high strength, high hardness, or high toughness, high hardness strengthen item, which makes the small-hole cutting more difficulty.
The material of making twist drill is high speed steel & hard alloy, the main material is high speed steel.
Here the small-hole cutting is in the difficult cutting material, there is various non-metal materials, strengthen item nonferrous metal, various difficult cutting metal materials.

Logistics supply chain is a network of suppliers, factories, warehouses, distribution centers and retailers where the raw materials are acquired, manufactured to products, which then are delivered to consumers.
Multi Agent Logistics Coordination A logistics supply chain is referred to as an integrated system which synchronizes a series of inter-related business processes in order to: (1) acquire raw materials and parts, (2) transform these raw materials and parts into finished products, (3) add value to these products, (4) distribute and promote these products to either retailers or customers, (5) facilitate information exchange among various business entities (e.g. suppliers, manufacturers, distributors, third-party logistics providers, and retailers).

Combined with the characteristics of hydropower, analyzes the causes of cracks in the turbine, materials, design and manufacturing, operation and so on.
The Reason of the Cracks The reason cracks should be multifaceted and has a certain relationship with the materials, design, manufacturing and operation.
Metallic materials under the stress state within the material inherent defects (pores, inclusions and cracks, etc.) at the first formation of micro-cracks, and to a certain form of the expansion, bringing together until a fracture caused by metal material or surface cracking.
By contrast with the Chinese material composition standards, sample composition meets ZG00Cr13Ni5Mo requirements.
