Rossello [4][5] and Ashraf Ragab [6] Mohamed’s researches indicated that the property of ITZ between aggregates and mortar in concrete would affect the crack’s extension route.
If the interface has exorbitant adhesive strength and excessive interface mechanical properties (strength, elastic modulus and fracture energy), the “trans-aggregate” cracks will exist; otherwise, the “along aggregate” cracks will exist.
At present, plenty of researches have been carried out on the interface and the concrete’s properties with the quantitative relationship between the interface phase properties and the concrete’s toughness indefinite nevertheless.
What kind of properties that the interface phase material shall feature to have the optimal toughness?
The 2D concrete model with random distributive aggregate is adopted to calculate the mechanical property of concrete with flexible interface phase material.

A porous tin coating with a dull appearance is produced in the affected areas.
Not only are the aesthetical values of the finished tin plate product affected but the corrosion resistance is also reduced.
Batch annealing prior to the tinning process is often a necessary requirement to produce the required mechanical properties of the final tinplate product and is usually conducted in a protective atmosphere to prevent the oxidation of the steel strips.
The dependency of the average size of the MnCr2O4 on the chromium content suggest the importance of the chromium content in the steel and that the supply of the chromium is the limiting factor for the growth of the MnCr2O4 spinel.

Many factors affect the photocatalytic activity of TiO2, such as TiO2 crystal type, particle size and surface morphology.
The photocatalytic properties of anatase TiO2 can be explain by the available Energy band theory of semiconductor.
As the pavement structure is used by porous asphalt concrete, after a period of time, the pavement can still keep the photocatalytic properties with the portion of TiO2 in the pavement pore.
The active life of photocatalytic technology is the key factor.
Mechanochemical synthesis of fluorine doped SrTiO3 and its photo-oxidation properties[J].

Therefore many studies on fatigue properties of high strength metals in long life region have been carried out [1-3].
However the effect of loading frequency on the fatigue properties is not fully clarified.
On the other hand, surface modifications of metals are also effective to improve the properties on wear, fatigue and so on.
Mechanical properties of the aged alloy were 0.2% proof stress of 1147 MPa, tensile strength of 1372 MPa and reduction of area of 38.1 %, respectively.
These mean that the base metal was not affected by nitriding and a crack propagates controlled by properties of the base metal, though the crack propagates at first in brittle manner in the nitrided alloy.

Stress and Strain Analysis of Asphalt Pavement Impacted by Temperature and Load Jian Li1,a 1Research Institute of Highway Ministry of Transport, Beijing, China, 100088 a jian.li@rioh.cn Keywords: Asphalt Pavement; Temperature; Load; Coupling Effect; Stress and Strain Abstract:emperature and load are the major factors of road surface deformation.
The influence of coupling effect of temperature and load is more significant than a single temperature or load factor.
The material properties of asphalt concrete is complicated, and its mechanical properties is depended on temperature and load.
Effect of load on the asphalt pavement Load is another important factor leading to the asphalt pavement rutting.
Within the calculated temperature range, the max increment of compressive stress spots at 12cm beneath the surface, which means the compressive stress of up-base is more affected by temperature changes.

CNC Cutting Performance in Processing Using Cool-air Cutting Technology Jing He 1, a, Guangsheng REN2,b 1 Department of Electrical and Mechanical Engineering Chongqing Engineering Polytechnic College, Chongqing 400037, China 2 The State Key Laboratory of Mechanical Transmission, Chongqing University, Chongqing 400044, China ahjlth@163.com, brgs_tiger@163.com, Keywords: Traditional cutting; Dry cutting; Oil solution cutting; Cool-air cutting technology; Life expectancy of cutter; environmental pollution.
Steel 45, alloy 2WCrNi and titanium alloy are analyzed under different cooling conditions; cutting life and processing quality are evaluated and contrasted to find out the phenomenons which affect the cutting life.
Alloy of titanium (Ti-6AL-4V) has good mechanical properties and excellent high-temperature deformation ability.
Tool wear will be significantly reduced when cool-air cutting technology is used in processing. 2) The attrition value of Flank under different cutting environments almost equal in initial wear stage (VB within 0.11mm).As the factors which influence the state of tool wear in initial wear stage is the form of the tool itself, the contact surface between Flank and finished surface is small (almost a line) and with high stress, so the tool wear rate is higher in primary stage.

Also, vanadium is an important alloying element in the production of iron and steel industries, due to its stable chemical properties, such as resistance to oxidization in air, salt solution, acid, and alkali solutions.
The main parameters affecting the vanadium extraction in NaOH solution were mass ratio of alkali-to-residue, reaction temperature, and reaction time.
Experimental factors and levels Level Factor R Tr (˚C) t (min) 1 3:1 140˚C 60 min 2 5:1 200˚C 120 min The results of L4(32) orthogonal experiment was presented in Table 4.
Thus, the most effective factors for vanadium leaching are reaction temperature and reaction time.
And, the reaction temperature and reaction time were investigated in the following experiments as the main factors.

Soil base resilience modulus is the main mechanical parameters reflecting the subgrade bearing capacity.
In addition to the special properties of loess soil, there are many other factors which lead to the diseases, including improper construction control, lack of filled soil compaction, poor drainage and unqualified materials.
Resilient modulus directly affects the pavement design, while，due to many testing method of resilient modulus and the influence factors such as soil, climate, geographical conditions and test method.

However, properties of glubam are quite different from both timber and steel.
However, it should be noted that because of the different structures and properties of materials, the properties and failure modes will differ a lot.
