Introduction Austenitic stainless steel and nickel-based alloy have been widely used in structural materials of nuclear power equipment due to good corrosion resistance and mechanical properties, and stress corrosion cracking (SCC) of these materials in the environments of the light water reactors (LWRs) is one of the main problems for the management of the structural safety and service life of nuclear power plants [1].
Stress corrosion cracking of austenitic stainless steel and nickel-based alloys in high temperature water is an electrochemical anodic reaction affected by corrosive environment, stress and material at crack tip.
Particularly, the introduction of the stress intensity factor (KI) as the basic mechanical parameters in last century makes the quantitative prediction of stress corrosion propagation rate of various austenitic stainless steel and nickel-based alloys in high temperature environment possible.
But how to improve the prediction accuracy of stress corrosion crack growth rate is still a serious problem due to the expensive experimental apparatus, long experimental period and many other factors [4].
In order to obtain the mechanical parameters more accurately, the sub-model technology was used in this study.

While for MLCP, its energy absorption properties decline continually by small margin as the RH increase in relative humidity range between 40%-95%.
The primary aims of this study are to: (a) compare the energy absorption properties of honeycomb paperboard and MLCP; (b) explore the differences of energy absorption properties of two paper-based materials in various ambient humidities.
Another method to evaluate the energy absorption properties of cushioning materials was by using energy absorption curves [1, 6-7].
Energy absorption properties of honeycomb paperboard and MLCP at different humidities.
While energy absorption properties of MLCP declined by small margin as the RH increase.

The workers of Faculty of Mechanical Engineering and Naval Architecture of University of Zagreb (Croatia) realised testing the influence of the position of products in the machine working area on the mechanical properties (tensile and flexural properties) of the product [2].
With polymeric foils better mechanical properties are achieved than with paper.
For both selected materials, a parameter study has been performed to optimize the process regarding part density, since porosity has a harmful effect on the mechanical properties of the part.
To predict the mechanical behaviour of FDM parts, it is critical to understand the material properties of the raw FDM process material, and the effect that FDM build parameters have on anisotropic material properties.

Many reports have described the manufacturing methods and mechanical properties of ultra-fine grained steels.
These tendencies imply that grain size affects not only yielding but also work-hardening behavior.
One factor which strongly influences these properties is grain size.
However, since little information is available on grain refinement in ferritic stainless steels, the possibility of grain refinement and the changes in properties with grain size in ferritic stainless steel are not yet well understood.
However, the average grain size in the cold-rolled and annealed specimens was hardly affected by the annealing temperature.

It has important significance to understand the heat-conducting property and simulate temperature field of geotechnical materials in northern China.
Temperature was one of important factors affecting TC.
The original loess-like soil in Changchun at different depths (0.4 m, 0.6m, 0.9m, 1.2m, 1.4m) and in different sizes in the same site were measured ,whose physical and mechanical properties were shown in Tab.1.

Several tests have been performed to check the modifications in glass ceramic mechanical properties.
Its properties are shown in table 1.
A heat affected zone, where the microstructure, composition and thermal-mechanical properties could be modified, is originated [5, 6].
To assess the variations in the mechanical properties, the glass panel was subjected to Vickers microhardness, toughness by indentation method and bending strength tests [8-10].
Modifications of mechanical properties in the machined zone and in adjacent areas were studied finding no substantial variations compared to the substrate without processing.

Interlayer lying between substrate and coating layer plays an important role on these properties.
For the coating layer, both morphology and properties must be considered.
Zirconium was selected due to its unique properties including high strength and ductility [6].
Therefore, it can be concluded that both the holding time and type of interlayer coating are the important factors on morphology of the coated film.
This should be due to different mechanical properties of interlayers.

In grey iron it is a powerful pearlite stabilizer which has favourable effects on its mechanical properties and serviceability.
In improvement of the mechanical properties, Sb showed the best results among some similar metals (Sn, Pb, etc.).
The antimony content detected in the wheel sample is considered in the 20th century to be ideal for the structural and mechanical properties of the wheel.
It was found that the antimony content was ideal in the whole wheel for achieving the best mechanical properties, according to the literature data taken from the 20th century.

Effects of deformation temperature and strain rate on deformation behavior of semi-solid 6061 alloy were investigated on Gleeble3800 thermal-mechanical simulator.
Because the flow stress formulation of the semi-solid material is affected by the strain, the strain rate, the temperature and other variables, it should be represented as a function of these parameters
Fig.8 and Fig.9 showed the effect of friction factor on the equivalent stress and strain.
The friction factor were 0.2, 0.4, 0.6, respectively.
It was also found that the lubrication condition had little effect on the deformation properties.

The elastic and plastic properties of the coating material affect differently the critical indentation depth and therefore the width of the range of the existence of the layered solid hardness within which the effective coating hardness can be determined.
Thus, studying the mechanical properties and the hardness of strengthened surfaces presents researchers with a dilemma.
It is shown that the elastic and plastic properties of the coating material affect differently the critical indentation depth and therefore the width of the range of the existence of the layered solid hardness within which the real coating hardness can be determined.
