., Ltd has researched the road performance of the ionic soil stabilizer, including the technical index of road base course, optimum mixture ratio and the mechanical property index[8].
Jones and Eng[11] has studied a sulphonated oil additive in order to found its action mechanism and characterize its action effect with mechanical property index.
However, the treatment mechanism and controlling factors of the ionic soil stabilizer are so complex that the treatment technology is far from mature, which involved regional geology, hydrology, climate condition and highway criterion.
Similarly, the mechanical properties of clay were also affected by PH.
The size, shape, arrangement, connection and micro-pore characteristics of internal structural units were observed by advanced microscope and SEM analysis to reveal not only the external physical and mechanical properties, but also the internal material transformation process of clay.

As a result, when the sintered temperature is about 1000°C and the addition of m-ZrO2 reaches 20wt%, superior main phases are HA and t-ZrO2, which improves the combination of mechanical and biological properties.
The use of synthetic HA is, however, limited to low load bearing applications due to its inferior mechanical properties (especially fracture toughness) compared to cortical bone [1-3].
Hence, many attempts have been made to improve the mechanical properties through the incorporation of ceramic second phases, such as ZrO2 [4], Al2O3 [5], and TiO2 [6].
The addition of ZrO2 in the form of particles [7-9] to HA matrix has drawn much attention due to its biocompatibility coupled with the tendency to enhance the mechanical properties of HA [10-12].
On the contrary, when the addition of yttria-stabilized m-ZrO2 is excessive, biological properties of composites are weaken.

The microstructures and properties were investigated for PFM.

B4C/Cu Layered and Graded Coating for PFM The high melting point of B4C related to its excellent thermo- mechanical properties makes this low-Z material suitable for using as PFMs.
But, the water quenching tests showed that the graded coating had better heat quenching properties comparing with the others.

Nonlinear face-face contact model between sampler and sediment is established by adopting the Mohr-Coulomb constitutive model as sediment’s material properties, and the friction and contact in the interface of sampler wall and sediment are well simulated.
The sedimentation characteristic is relevant to size distribution, siltation time, embedment depth, sedimentary environment, permeability and other factors.
That whether the sampler can remain the status quo ante of sedimentation directly affects sampling results.

LCBER was cured with polyamide-650 (PA-650) and the thermal and mechanical properties were evaluated.
It’s well-known to us that the combustion of biomass is an important factor of carbon dioxide production.
The natures of CB-based epoxy resin, such as adhesive shear strength and thermodynamic properties, were also tested.
This would be probably due to the good wetting property of LCBER to plywood.
The low molecular weight portion of LCBER-60 may affect the thermostability of cured compound, which leads to the decomposition of cured LCBER-60 at a relatively low temperature.

The assessment of the fretting fatigue strength and life of any component is a complicated issue due to the many parameters affecting it, the complexity of the stress fields cyclic variation during fretting and the uncertainties associated to the contact conditions.
Introduction Fretting fatigue denotes the detrimental effect on a material’s fatigue properties arising from the cyclic sliding of two contacting surfaces with small relative displacements between them.
Models are not perfect and there are always uncontrollable and unpredictable factors that need to be taken into account experimentally.
All of these factors create a new source of errors in the calculated stresses and those actually produced, with the consequent effect upon resistance to fatigue.
If the specimen and pad materials have the same mechanical properties, the normal pressure distribution does not change and tangential tractions appear at the interface.

Introduction Anthropogenic accidents or catastrophes cause an emergency situation, the sudden occurrence of which leads to significant human loss or damage to people, socio-environmental and economic losses, the need to protect people from harmful effects on the health of poisonous, radioactive substances, bacteria, trauma and psychogenic factors, carrying out rescue, emergency medical and evacuation measures, elimination of the negative consequences which have developed [1].
During the operation of structures, there is an accumulation of damage in the structure of the metal, which causes a change in its mechanical properties [4].
In addition, the combination of the ultrasonic pulse method and the elastic rebound method do not affect the accuracy of interpretation.
Fig. 1 Appearance of test samples of reinforcing steel prepared to determine the strength characteristics by a “thread cut” (for example, a sample of Ø14 mm reinforcement steel, class A240C) Simply put, the experiment was reduced to the destruction of connections that were formed from the test screw and the test material (samples of fittings, whose properties were determined by the “thread cut”).
A deeper study of reinforcing steel properties after temperature exposure is much greater than it was considered in the normative literature showed that the yield strength of steel in comparison with the indicator to temperature influence decreases by 2.9% (at 800 оС), by 3.12% (at 900 оС) and 4.05% (at 1000 оC); temporary resistance – by 2.7% (at 800 оС), by 2.9% (at 900 оС) and by 3.9% (at 1000 оС).

Also, through various construction performance tests, author confirmed the possibility of stiffness affecting the construction work.
It is a term that represents a qualitative state to the last, but this phenomenon itself includes very complex physical and chemical factors.
In this experiment, to verify the effect of the anti-stiffening agent, the anti-stiffening agent was added to the concrete sample in 30 minutes after the mixing, and compared the properties with of the base concrete as the control.
Influence of Concrete Stiffness on Construction Performance In this chapter, an influence of the stiffening behavior of concrete on construction performance was evaluated from the viewpoint of filling and pumping properties.
This suggests that the use of a stiffening agent may improve the filling properties of concrete

In this study, a U-channel bending test with tension were used to evaluate the surface damage resistance of dual-phase (DP) steel against heat treated Mo-Cr cast iron, and a numerical simulation model of the U-channel bending were developed to analyze the interface contact pressure on formed part that is an important influencing factor of surface damage.
The mechanical properties of the tested DP steels are listed in Table 1.

The mechanical properties of the DP steels are summarized in Table 1.
For the high pressure region the magnitude of the contact pressure increases with increasing of the tensile strength which is because compassion bending stress proportionally relates with the strength of material, and for the low pressure region its magnitudes are almost the same which are only affect by the friction that relates to the blank holder force on the flange.

The relative vibration between the tool and the workpiece can make machining surface produce vibration mark, it will affect the surface quality and using performance of workpiece seriously; Dynamic alternating load acts on process system continuously, the cutting tool is worn easily, even causes tipping, so as to reduce the tool life [3, 4].

The size of the feed should be reasonably selected according to the workpiece materials, tool geometric parameters and machine rigid factors.
Cutting speed will affect plastic deformation, the processing surface quality and metamorphic layer.
