In contrast to flow behaviour at high strains or anisotropy of metals at elevated temperatures the inelastic heat fraction that also affects these properties isn’t well investigated at least for AHSS.
On the basis of this results the concept of stored and dissipated energy fractions were introduced and the factor (also known as, which is used in this paper) was defined as: . (1) This formulation describes the relation between the heat power and the mechanical power .

The mining of upper coal seam, mechanical properties of roadway surrounding rock and the vertical distance between roadway and upper coal seam were three key factors of roadway maintenance and rational arrangement (Shi-Liang Lu, 1984 and 1993)[1,2].
The displacement of roadway surrounding rock under condition of close cross mining is seriously affected by the overall displacement field after msining (Wen-Bing Xie, 2001)[4].
Fig. 2 Numerical calculation model According to geological data provided by Dingji coalmine, we selected the rock mechanical parameters as shown in Table 1.
Mining pressure began to affect roadway while the size of coal pillar was 105 m, as the face kept on advancing, the effect of mining become more intensive.

In the long term of vehicle service period, the environmental factors have significant influences on the adhesively bonded joint service performance, such as temperature, moisture and corrosion, etc.
Results showed that the adhesives have different mechanical properties with temperature and the simulation predictions on the joint fracture toughness matched well with the experiment results.
The mechanical properties of Q235 steel and AA6016 aluminium alloy are shown in Table 1.
The adhesive mechanical properties, curing conditions and toughness comparison are shown in Table 2.
To understand the asymmetric effect in mechanical properties of the substrates, steel and aluminium alloy are taken as the substrate materials in each joint separately.

However, it’s difficult to control the processing parameters, because many factors involves.

It’s an effective method for measuring and monitoring of structure response of asphalt pavement with sensor to evaluate materials performance and to verify the validity of mechanical model.
The agreement of experimental observations and calculative results shows the feasibility of FBG sensors in temperature and strain monitoring of asphalt pavement structures and the validity of mechanical model.
Introduction The effect of temperature on pavement performance is generally considered to be a very important factor since it directly affects the structural capacity of pavements.
Thermal expansion and contraction adversely affect asphalt pavements, mainly by causing thermal transverse cracking.
Comparison of Monitoring and Calculated Results With the asphalt pavement being treated as an elastic layered system, we calculated the analytical solutions of temperature and strain by transfer matrix method, and material properties are indicated below: Asphalt surface: E1=1500MPa, μ1=0.25, a1=2.16×10-5 1/°C, κ1=2.8×10-3, λt1=1.0, h1=0.1m; Macadam base: E2=700MPa, μ2=0.25, a2=1.5×10-5 1/°C, κ2=3.0×10-3, λt2=1.2, h2=0.25m; Soil subbase: E3=40MPa, μ3=0.35, a3=5×10-4 1/°C, κ3=2.5×10-3, λt3=1.0.

Moreover, the initial density affects the thermal deformation of powder compact to a certain extent.

Each particle composed of powder compact has the same properties with usual complete compaction, so it usually has characteristics as the usual metal.
The initial density affects the thermal deformation of powder compact to a certain extent.

Buildings and structures, from the moment of their erection and at all stages of the life cycle (in other words, during operation) affect our safety.
The alternating loads and the influence of external factors help to reducing the load-bearing capacity of these structures.
The state of the reinforced concrete structure is affected by various technical and operational factors.
Decrease in strength of concrete is one of the main factors reducing the load-bearing capacity of reinforced concrete poles [4, 6].
The above signal parameters for the survey of the underground part of the support depend on the physical properties of the ground. 

Constructive problem solving processes gradually evolved as increased knowledge about materials and their properties and modeling as growing complexity and the complexity of the products.
Perhaps the most affecting to the constructive problem solution the using of computers and their application is compared with the invention of the printing press.
Since the problem is not wholly described now, it is difficult to cope with the dynamic properties of the unknown environment

Several factors may affect the guided wave propagation such as environmental conditions, material structure and the presence of stress in the waveguide.
TOFσ is affected by the acoustoelasticity effect and the material elongation caused by the applied load as follows.
Two analytical expressions of fundamental torsional mode velocity propagating in a medium under mechanical stress are studied based on the acoustoelasticity effect.
The expression depends on the material properties including the Lamé and the Murnaghans constants and the applied stress.

Two competing factors affect the wear rates of the composites.
Therefore, the composites incorporating graphite do not work for wear reduction, as the debit in mechanical properties is larger than the very small benefit in friction reduction.
