A great quantity of work has been carried out to investigate the influence of orientation and rotation speed on the mechanical property of nickel-base single-crystal superalloys.
Most of the methods in the previous study are deterministic and the uncertainties in the values of the parameters that affect creep life are not incorporated.
The variations of these two factors will directly influence the creep life variations.
Since the statistical properties of random variables have been gained, the dispersion of ft is easy to be calculated based on Monte-Carlo method by random samplings of the base random variables.
Monte-Carlo method, as a numerical simulation method, is used to obtain these statistical properties and the reliability of creep life based on the finite element code, and the precision is guaranteed by enough simulation samplings.

When the strength of concrete gets higher, some of its characteristics and engineering properties become different from those of normal-strength concrete (NSC) [1-3].
These differences in material properties may have important consequences in terms of the structural behavior and design of HSC members.
The Initial Tangent Modulus of Elasticity It is well known that the modulus of elasticity of concrete provides a bridge between stress and corresponding strain and represents one of the most important mechanical properties of concrete.
Although there are a variety of factors having effect on the elastic modulus such as the properties of mortar, properties and proportions of coarse aggregates, size and shape of specimens, wetness and dryness of the concrete at the time of testing, rate of loading, and method of obtaining the deformations [4-7], provided the test conditions remain the same, the effect of the type of coarse aggregate used to make the concrete can be singled out as the most significant parameter [6,7] that affects the modulus of elasticity [2].

zone (HP06~HP21), anchor cable tensioning affected zone (HP31~HP61) and displacement stable region (HP76~HP113).
The pile wall section where HP06~HP21 monitoring points were laid was not tensioned by anchor cable in the first stage monitoring, and it was mainly affected by the filled soil inside.
Conclusions Through the monitoring of slope retaining structure, the safety and stability situation of high backfilled soil slope of a large power plant in karst area with developed karst in Guangxi is studied, and the conclusions are as follows: (1) the anchor cable tensioning is the most important factor affecting the displacement and stress changes of the slope protection piles, tensioning resulted in a surge of the reinforcement stress and displacement of the piles in the tension zone towards the inside filling after construction.

Introduction Many concrete structures can be affected by high strain rates coming from different sources, like natural hazards (tornadoes, earthquakes or ocean waves) or industrial accidents [1].
The dynamic increase factor (DIF), defined by the ratio of the dynamic strength to the static strength of the material, is used to model the strength enhancement by the strain rate effect.
A total of one hundred samples were tested by this procedure in view to assess the dynamic micro concrete behaviour and deducing its properties.
This behaviour is analysed through the material mechanical characteristics evolution according to the deformation rate.
The model presented in this study evaluates the compressive dynamic increase factor (CDIF) of the material as a function of strain rate over a wide range.

The analysis of thermal cycle formed due to moving point heat source is important because it leads to variation in mechanical properties such as hardness, tensile strength and microstructural behaviour, also the appearance of residual stress.
The thermophysical properties of AISI 1090 and experimental process parameters are tabulated in Table 4 and Table 5 respectively.
The reason is influence of heat affected zone formed near T1 and T2.
By application of experimental temperatures keeping other thermophysical properties (refer Table 4) as constant, rate of cooling has been analyzed in three different locations from fusion line (z = 36mm, 72mm and 108mm) as depicted in Fig. 13.

(1) By means of experiment of single factor, the leaching time, ore pulp liquid-solid ratio, concentration of NaOH, amount of K3Fe(CN)6, leaching aid CaO2 and so on were respectively investigated about their effects on the gold leaching rate.
The possible reason is that too much K3Fe(CN)6 reacts with other metal salt in ore pulp, which affects the leaching process.
For one thing, excessive concentration of CaO2 can damage K3Fe(CN)6, affecting the leaching process.

The corresponding shape factors are 1.41, 1.21, 1.86, and 1.19, where shape factor = perimeter 2/(4⋅π⋅area).
Thus, the higher the shape factors the more irregular the shapes of the eutectic Si particles; the unmodified morphology exhibits higher shape factors than the modified one.
