Springback is one of the key factors to influence the quality of stamped sheet metal parts in sheet metal manufacturing areas.
It is influenced by several factors, such as sheet thickness, material properties, tooling geometry, friction and etc.
Design variables exhibit different properties depending on the parameter they represent.
One of the most important factors to be considered when performing a numerical analysis is to use a constitutive model that accurately captures the behaviour of the material.
Table 1 shows Fe355 material properties used for blank.

Introduction It is well established that high microporosity can result in dramatic deterioration of the mechanical properties, and in particular of fatigue properties.
Because of the complexity of the physics associated with microporosity formation, assessing the hierarchy of the process and material parameters that affect microporosity is not a trivial task.
(10) where A and Ke are the activity and equilibrium coefficient of pores respectively, and 101,325 is a unit transformation factor.
(13) where α is a transition factor from gas and melt mixture to pore, and Ptot is the total melt pressure on the pore calculated with Eq. 1.
The transition factor is evaluated by comparing model predictions with experiments.

Generally speaking, from the previous critical review, it can be stated that using LRB as a base isolators affects the dynamic response of RC buildings causes a rise in the natural period, roof displacement and a reduction in the roof acceleration, base shear and storey drift ratio.
At the two ends of the columns, the nonlinear hinge properties are assigned (P-M2-M3) hinges, these are based on the concrete compressive strength (fc’=40MPa) and steel yielding stress (fy=400MPa).

The principal properties are shown in table1.
It has many good technical performances, including: (1)The lightweight insulation hollow block has good thermal insulation performance and a certain degree of mechanical property.
To study the fire resistance performance, the grillage shear wall was fired at 2000℃ for 2h at fire protection research laboratory of the ministry of public security in Tianjin, the result showed that there was no obvious damage on the surface and the blocks have good fire-resistance properties [5]

The vibrating tube should be placed in right place first in order to prevent affecting the original locations of reinforcing steels

The main advantage of dispersed fuel elements is that their thermophysical and mechanical properties are mainly determined by the properties of the matrix material, and the most of fission products are retained in the fuel particle.
Despite of the good irradiation resistance of alloys, as well as the high thermophysical properties of dispersed fuel elements, it has not been possible to fully realize the potential of metallic fuel.

However, the values of the pre-exponential factor depend very strongly on this choice of degree m.

Introduction Predicting the remaining bearing capacity of corroded RC members serves as a vital factor to assess the durability and longevity of a reinforced concrete (RC) structure.
Also the theory of limit equilibrium was applied during analysis to yield the final conclusion.According to Higgins and Farrow's[3]research on how the stirrrup corrosion degree under different stirrup ratio affect test beam, they concluded that the check of appearance damage can't be the sufficient condition for distinguishing the structure properties of corroded RC beam,and they also indicated that the conditions of local corrosion of stirrups in different positions had great influence on distinguishing the structure properties of corroded RC beam.Another approach was developed by Zhao and Jin[4], where the previous conclusions on this issue were discussed and evaluated.
By considering the influence of steel bar corrosion on their cross-section and mechanical properties, as well as the reduction of the effective section area of the concrete, a shearing capacity assessment formula of RC beams with corrosion stirrups is proposed based on the shear capacity formula given by the actual Chinese code for the design of concrete structures(GB50010-2002).
After reaching the ultimate shear strength, the stirrups and oblique bars yield , therefore ,, combined with equation (1) , the shear force is present with (5) where is the angel between diagonal crake and horizontal directivity, and is affected by the oblique stress of the concrete .

Even though the presence of damage is generally accounted for, at the design stage, by the use of very conservative safety factors [4], more advanced damage tolerance concepts [5] are being gradually incorporated in the design process of critical elements of composite blades, so as to take full advantage of the weight-saving potentiality offered by sandwich materials.
Stress-based failure criteria and a sudden property degradation strategy were adopted in [15] to simulate the damage induced by low-velocity impact on the glass-fibre woven skins of sandwich beams.
The elastic and fracture properties of the composite layers used in the FE model, obtained by a series of experimental tests or provided by the material manufacturers, are listed in Table 1.

Boyano et al. [12] prepared the catalysts of V2O5/AC and V2O5/Al2O3 by impregnation method and studied their catalytic and mechanical properties.
Gao et al. [13] studied the catalytic properties of V2O5/AC in the temperature range of 100-300℃, at the GHSV of 24000 h-1.
These good properties make carbon nanotube become a new type of catalyst support, furthermore it has attracted the attention of many scholars in recent years.
For some kinds of the catalyst, however, NO conversion decreases first and then increases with the increase of temperature.Therefore, temperature is the important factor affecting the catalytic activity.

It is also to be noted that formulation of the heat transfer problems in both cases was analogous to the real growth run, i.e. only the verified thermal boundary conditions were introduced as constant values into the domains being simulated (at the peripheries of water-cooled chambers and copper current connectors), while maximum temperatures inside the growth reactors were determined by the amount of heat power supplied to the heaters, and temperature dependent material properties of the internal reactor furniture.
The temperature dependences of the material properties were taken from the product specification lists provided by the manufacturers and/or found in the materials handbooks.
It is appropriate to note here that, depending on the source material properties, the overcooling criterion of the top surface can be estimated according to the onedimensional relationship: (a) (b) Fig. 3.
However, it has been demonstrated [14] that 2" represents the practical limit of SiC ingot length, which can be grown within the conventional furnace design even when the source material availability is not the growth limiting factor.
However, changing the pyrometer opening diameter automatically affects radial gradients in the crucible that might be undesirable if the gradients increase.

Introduction Ship accident, especially as a result of the fire accident, is the most dangerous part of marine disasters, caused huge losses of life and property.
Due to the special working environment of the ship, especially on warship, the fire extinguisher is facing all kinds of threat: such as the mechanical vibration of the ship, high temperature in stokehold or on the deck which is exposed to sun, low temperatures when the ship sailing in cold regions, salt corrosion, shock impact when the ship swings in a stormy voyage.
All these factors may lead to fire extinguisher abnormality and unable to extinguish ship fire effectively.
The presence of the deficiencies and disadvantages of the fire extinguishers in the domestic market discussed above, will definitely affect the ship fire fighting ability in future fire disasters.
China's national standard also lack of sufficient consideration of ship's mechanical heat and solar thermal radiation.
