With the increasingly widespread application of high-strength steel(HSS), tailored properties, namely different mechanical properties required in different regions of the same part, have been proposed, in order to achieve the matching between mechanical properties and safety performance of motor vehicle parts.
However, with the more widespread application of high-strength steel, the matching between mechanical properties and safety performance of motor vehicle parts has been proposed, and to be more concrete, different mechanical properties are required in different regions of the same parts, namely tailored properties.
This work has discussed the influence of increasing gap on the mechanical properties of the parts experimentally.
The mold temperature determines the size of the thermal resistance between the blank and the mold, thus affecting the cooling rate of the blank.
Hence the blank of the transition region reached its lowest cooling rate considering the two factors, resulting the lowest hardness.

These factors have important effects on the mechanical properties of propellant.
As a result, the mechanical properties of HTPB propellant are remarkably enhanced.
On this condition, formula 4 has better mechanical properties than formula 2, because the content of binder in formula 4 is larger, the effect of the matrix cross-linking net structure of binder on the mechanical properties has emerged.
It can be concluded that bonding agent can remarkably enhance the mechanical properties of propellant.
The interface reciprocity between the binder and filling particles is the primary factor to the mechanical properties of HTPB propellant.

For this reason, there are many studies in the open literature regarding crack mechanisms in homogeneous or functionally graded materials (FGMs) involving isotropic or anisotropic material properties.
By using the stiffness parameters from Krenk [4], the dependency of the stress intensity factors on the material properties was investigated.
The novelty of this study comes from introducing the orthotropic material properties and surface crack conditions to the finite element method.
It is noted that, the change on the normalized depth of the crack, , greatly affects the mixed-mode stress intensity factors, and .

Summary on research advances on the reservoir bank instability Zulian Zhang1,a,Ying Huang1,b 1Kunming University Science and Technology,Yunnan,China,650500 azhangzulian@2008.sina.com, bhuangying3764@sina.com Keywords:Bank instability,Influence factors,Stability analysis,Instability mechanism,Treatment measures Abstract.The reservoirbank instability is the outcome combined the action of the external factors withthe actionof the internal factors.
The width of thereservoirbank instability is relatively smaller when thereservoir bank is composed of the clay of the good physical properties and mechanical properties and the soil of weathering by the sedimentary rock.
The geologic structure is an important factor affecting the integrality of the reservoir bank rock mass.The attitude of the rocks,the thickness of stratum, the upper and lower sequence of each layer,the exposed position of each layer,the geologic structure of the reservoir bank rock affect directly the reservoir bank stability.
The external factors The rainfall, thereservoir water impounding and the water level fluctuation The changes of hydrological and geological conditions of thereservoir bank rock and soil caused by the rainfall,thereservoir water impounding and the water level fluctuation will change the properties ,the strength,the structure and the status of the reservoir bank rock ,and decrease the mechanical and physical properties of the reservoir bank rock and soil.These are important externalfactors inducing the reservoir bank instability .
The sensitivity analysis of theinfluence factors Wantao Zhang[4] et al. selected six factors about the angle of internal friction,thereservoir water level fluctuation, the earthquake acceleration coefficient, the cohesion, the unit weight and the pavement load to carry out the sensitivity analysis of the influence factors.The results showed that the angle of internal friction, thereservoir water level fluctuation and the earthquake acceleration coefficient were the very significant influence factors and the cohesion was the significant influence factor of the reservoir bank stability.Ran Ran[5] et al. pointed out that the bank angle and the height of the reservoir bank were the key factors to affect the reservoir bank stability in the geometry index of the reservoir bank.
