Currently, a lot of documents about blanking research on metallic material were put forward, for example, the blanking process on foil sheet with tiny hole was researched by Xu Jie [2], the blanking material and thickness affecting the blanking force curve and maximum blanking force were researched by Hong Guo-hua [3], however, few document about blanking research on non-metallic material was put forward.
There are some differences during separation process of metal and plastic blanking due to the different material properties, and the cross-section qualities after blanking also have their own characteristics.
The mechanical properties are as follows: modulus of elasticity is 1890 MPa, poisson ratio is 0.422, yield strength is 96 MPa, tensile strength is 152 MPa [5, 6].
The unilateral blanking clearance value of the insulation spacer is adopted as 0.02t via considering influence of blanking clearance on the above factors synthetically.
The blanking speed value of the insulation spacer is adopted as 90 mm/s via considering the influence of blanking speed on the above factors synthetically.

The traditional way of acquiring the formed archwire curve is based on manual operation, which will randomly bring numerous errors caused by human factors.
Introduction In human growth and development process, malocclusion is a common kind of mouth disease due to genetic and environmental factors.
Traditionally, formed archwire is bent by orthodontist or technician based on manual operation, which will randomly bring numerous errors caused by human factors [2].
But the springback properties of archwire which is a major factor to effect the experimental result was not considered.

With respect to application and properties of AISIH13 tool steel, electrical discharge machining is well known method for its machining.
Electrical discharge machining (EDM) is known to be applicable for conductive material regardless of their physical and mechanical properties [1,2].
Also the values of R2 (Table 6) confirm that the relationships between the independent factors and responses can adequately be explained by models.
These values show that the relationships between the independent factors and responses can adequately be explained by models.

Significant microstructural changes in the stir and thermo mechanically affected zones (TMAZ) have been observed previously [5].
Base material properties obtained, at room temperature, via uniaxial tensile and hardness tests are shown in Table 2.
Element Al Mg Mn Fe Cr Weight (%) 93.38 5.26 1.02 0.19 0.15 Table 2 – Mechanical properties of 5083H111 aluminium alloy at room temperature.
At elevated temperatures, additional thermally activated and time-dependent factors are acting in combination with mechanical fatigue.
The elevated temperature tensile properties of AA5083H111 also indicate a marked decrease in strength at 200ºC as shown in Fig. 7.

It is relatively very stable material with high lifetime, but in most of the cases is during its use exposed to various destructive factors.
It could be for mechanical straining, temperature, but especially effect by aggressive gases and liquids.
This is very clear in environment with higher concentration of aggressive factors which degradates surface layer of the concrete and allows gasses and moisture later impact throw pore tracts reinforcement in construction.[1,2] This in its final consequence leads to gradual degradation above all venerable parts, cement matrix and later to corrosion of reinforcement in concrete.
Properties of building structures protected by these materials, as for example resistance against water pressure, resistance against oil, gases, and many chemicals has been already many times proofed and described. [3,4,5] Functional principle Crystalline products are dry powder compounds composed of Portland cement, silica sand and many active, proprietary chemicals.
As can be seen on Fig 2, even after 18 months in effect by concentrated SO2 medium impact, results of S2 treatment did not show any dramatical decrease of water tightness properties.

Historic structures are made of different types of masonry with significantly different properties.
As a rule the information on mechanical properties of masonry components has to be obtained by testing.
Due to large variability, material properties are commonly assessed on the basis of tests.
To enhance estimates of fk and fd, a simplified probabilistic model of masonry strength f is proposed here (considering Section 3.2 of [5]): f = K (θfb fb)α (θfm fm)β, (3) where θ = uncertainty in estimation of the mean strength by a test method (possibly using appropriate conversion factors).

Then, the hardness test, thinning rate analysis and 3D curved surface scanning were performed to check the mechanical properties and external dimensions of the finished products of hot stamping.
Introduction In recent years, the automotive industry is making an effort to reduce the vehicle weight for reducing the CO2 emissions while maintaining high strength properties of vehicle components.
However, it affected the thinning condition of the component after the final forming in the control of the pressing force, which is the focus of simulation analysis and exploration.
Fig.11 The 3D scanning results show the maximum deviation is 1mm Summary This study used CAE software for simulation analysis, and used die verification to confirmed the rupture factor resulted in the hot stamping process of a complete 1.4mm-thick 15B22 boron steel sheet.
The validation results are as follows: (1) in the process of M-form structure forming, the setting of the pressing force has a great impact on the formability of the sheet metal, and can effectively reduce the thinning in the R angle area, which has been verified from the experiments; (2) the correct CAE analysis plays an important role in the formability and mechanical properties, and can enable the door impact beam to have a uniform hardness distribution after being formed; (3) 3D measuring of the finished product, the scanning results show that the maximum deviation is ±1mm, consistent with the general automotive parts assembly accuracy requirements.

The method and quality of grinding have a significant impact on the technical properties of NC: fractional composition, nitrogen content, viscosity characteristics, solubilities, average degree of polymerization, sorption and physico-mechanical properties, which must be taken into account when optimizing the rheological and technological characteristics of the obtained cellulose nitrate compositions.

Introduction Designing a pressure vessel for extremely high pressure condition is quite complicated and required detail consideration in many aspects including permissible stress level, definition of operation, failures criteria, material properties.
The location of damage affects different modes of vibration differently.
The most important factor affecting the cost of the pressure vessel is the maximum pressure at which the system is designed to operate.
Therefore, a vessel with this thickness is safe if the safety factor is 1.

There are many factors on effective reinforcement depth of dynamic compaction, but can be divided simply into two sorts [9].
The first one is internal factors which mainly include the property of the soil such as grain size distribution, density, degree of saturation and so on, and the ground condition such as different soil thickness, buried order, and underground water level, etc.
The second one is the external factors which mainly include construction technology such as hammer weight, hammerhead shape, hammer bottom area, drop height, tamping number and single rammed energy, etc.
The effective reinforcement depth in site2 test is deeper than that in site4, which means if the thickness of filling replacement is in same condition, the effective reinforcement depth would be larger for those materials having well physical and mechanical properties and well graded.
If the thickness of filling replacement is in same condition, the effective reinforcement depth would be larger for those materials having well physical and mechanical properties and well graded. 3) The filling replacement using medium-coarse sand with 4m thickness and the gavel sand with 3m thickness are relatively reasonable for the first phase of Brilliance BMW's second factory project to satisfy its requirement of bearing capacity.
