In extrusion stretch bending process, there are many factors which affect springback of the workpiece such as mechanical properties of the material, friction condition and process parameters.
The springback of same batch of extrusion is different at same forming parameters because of the variation of the mechanical properties of the material and the friction condition.
The results from the experiment state that the intelligent control method can suit the variation of mechanical properties of material and friction condition and improve the geometry precision.
Introduction There are many factors which affect springback of extrusion stretch bending forming, such as mechanical properties of the material, friction condition and process parameters and so on.
The traditional stretch bending method can't suit the variation of the mechanical properties of the material and friction condition and lead to low forming quality.

This study outlines the influencing factors of the conductive properties for carbon black filled conductive silicone rubber.
Silica added can affect the conductive properties.
Its conductivity is related to rubber matrix, types of filler, filler content as well as temperature and other factors.
The conductive silicone rubber has good electrical and mechanical properties and become a composite material[2-3] which is most widely used.
In the adding amounts up to 3%, the compound has the maximum conductive properties, if we continue to increase the amount, the conductive properties will be affected

The mechanical properties (that refer to the above mentioned wallettes), were taken from [2] (Table 1).
For each mechanical property a factor of original property, i.e. the ratio of the same property in damaged to undamaged conditions, was calculated.
The column titled 25 exp reports the values of severity and factors of original property of tests on 25 cm thick wallettes of traditional brickwork [3].
The same severity on two different thicknesses, i.e. 38 and 51 cm, does not originate significant differences in the factors of original properties, except for the E0,th/E0 ratio.

The rock masses containing joints have completely different mechanical properties with the intact ones.
The rock mass containing joints has completely different mechanical properties with the intact one [1-7].
The results show that the mechanical properties of jointed rock mass are significantly affected by the direction, length, filling material, degree of closure, connectivity rate and etc. of containing joints.
Although there has been some research on the mechanical properties of rock mass containing throughout joint cracks, as to the rock mass containing intermittent joints, for the complexity of its mechanics properties, it's still necessary to make a further exploration on its mechanical mechanism.
Prefabricated joint is the main factor that affects the failure pattern of rock mass.

In the present work, the effects of sintering temperature on physical and mechanical properties of HA/YSZ nanocomposites were investigated.
However, the processing parameters are the main factors that controlled the properties of the ceramics.
This result correlates with densification properties.

Safety assessment is generally done by conventional mechanical methods such as uniaxial tensile and fracture mechanical test, etc.
For example, nondestructive methods are needed to determine properties in a specific parameter.
This technique can nondestructively evaluate various mechanical properties such as residual stress, tensile properties, and fracture toughness by analysis of the indentation load-depth curve [1-3].
Tensile properties measurement using IIT Tensile properties can be evaluated by defining representative stress and strain with parameters obtained from instrumented indentation tests using a spherical indenter.
The tensile properties measurement used a WC ball indenter (radius 250 µm).

Keywords: weld, double embedded cracks, stress intensity factor Abstract: In this paper, double embedded elliptical cracks in a weld of pressure vessels under tension was taken into consideration, and stress intensity factors at the crack tip were calculated with the emphasis on the interaction between cracks.
Propagation of the group cracks is not only influenced by factors like the plate thickness, embedded depth and cracks shapes, but also by the interactions from each other.
Material properties of the weld and the stress intensity factor calculation methodology are the same as those of the previous paper.
But KI0/ks0 increases rapidly, meaning that SIF at this position is greatly affected by the crack interaction.
Calculation of the stress intensity factors for elliptical cracks embedded in a weld under tensile loading I: single crack.

However, these phases deteriorate the high temperature mechanical properties and also affect the oxidation behavior of ceramics composites.
III.3 Mechanical properties For both sintering aids, the mechanical properties results were similar.
The inhomogeneous mixture may be responsible for a decreasing of mechanical properties [27].
This behavior can produce mechanical properties anisotropy, principally, the fracture toughness [28-29].

Factors Influencing the Workability of DSCC Steel Fiber.
Steel fiber in DSCC is one of the main considerations as it will affect the mechanical properties and workability of DSCC.
Thus, it gives better mechanical properties to the concrete.
The inclusion of steel fibers not only improves the mechanical properties but improve the durability properties such as water permeability.
