Besides the mix design, fiber distribution is another crucial factor for strain-hardening properties of ECC [5-7].
Fiber wettability in the fresh ECC is regarded as the key factor to cause different fluid properties, Poor wettability can increase the entangled fiber clumps and hence greatly reduce deformability of the fresh ECC.
More efforts should be implemented to quantify the effect of a factor and comprehensive several factors on fiber distribution so as to maximize the reinforcement efficiency and thus optimize ECC performance and economize cost of product.

The weights of other factors, as listed in Table 1, show the differences among critical factors based on land use.

Introduction One of the most challenging problems of the material science is the influence of hydrogen on the mechanical properties of materials.
The mechanical material properties degrade because of this hard interaction.
Therefore, the factors of sorption α and desorption β of hydrogen are a linear function of strain.
It allows one to take a linear relationship between these factors (3) The dependence (1,3) describes the material properties modification during the hydrogen redistribution within the material.

The results indicate that the mechanical properties of the composite materials are improved after adding copper-coated carbon fibers.
The carbon fiber in the composite materials are prone to be pulled out, peeled off or shed when it is subject to load; these factors severely limit the applications of the composites.
The mechanical properties of theself-lubricating composite materials The mechanical properties of the self-lubricating composite materials reinforced by carbon fiber are shown in Table 2.
The optimum mechanical properties are found when the carbon fiber volume fraction is 11%: the hardness reaches 57.8HV and the strength 222Mpa.
The mechanical properties first increase, then decrease with the increase in carbon fibre volume fraction.

For synchronous motor [4], all the heat source is from the stator, the generated heat will affect machining accuracy.
On the one hand, the wall thickness has a greater effect on the cooling of the stator, and directly affecting the total area of cooling.

Introduction Up to date, there is no comprehensive procedure for evaluating the explosion action on a destructible medium which would take into account all the factors affecting the explosion result.
As a result, the elongated charge explosion energy transmitted to the medium in a particular section of the hole (well) depends not only on the EXP amount per unit length of the hole (well), but also on the entire charge explosion energy, explosion development over time, physical and mechanical properties of the medium along the hole (well) length.
The power characteristics of the impulse pressure are defined by: · charge structure; · charge weight; · EXP properties.
And by the equation of the shock adiabat of the pad material compression: where – initial density of the pad material; – shock adiabat factors of the pad material.
In addition, the main crack final length is affected by the relative distance between the ECC and the hole wall, which determines the initial cumulative "knife" digging depth and the physical and mechanical properties of the rock block being destroyed.
