Thus, only by getting to know characteristics of particulate media could system react to various disturbances, do a "self-organization" while factors’ change happening in order to meet the needs of engineering properties and get to know the microscopic characteristics of accumulation body well.
So the research of interior properties needs to be strengthened.
Instability mode of accumulation slope Instability and failure mode refers to damage of physical and mechanical deformation mode occurs on accumulation body under the main influence or control factors.
Contacted surface is the first discontinuous surface, as affected by groundwater and other factors, it usually has lower mechanical strength indicator, in addition, pour ​​water pressure and penetration force caused by underground water is also affected.
Impact factors of slope have an effect on slope instability model.

Because of these properties, PC has also attracted scientists to evaluate various studies on PC materials in the last few decades.
Several studies are carried out to characterize the static and dynamic properties of PC[1]–[7].
Johnsen et.al [14] reported he collective summary of properties of PC plate under the mechanical , Ballistic and aging behavior.
The properties of PC is evaluated by author as per ASTM standard using stress-strain graph obtained from universal testing machine and the evaluated properties is reported in [3].

The friction coefficient of composite is scarcely affected by the alumina content.
To improve the mechanical properties, particularly fracture strength and toughness of Al2O3 ceramic composites, Mo-based composites reinforced by in-situ Al2O3 ceramic particles were developed in this paper, and the properties were researched.
So the actual density of composites depends on the combined action of above two factors.
The friction coefficient of composite is scarcely affected by the alumina content.
The friction coefficient of composite is scarcely affected by the alumina content.

The paper presents the results of the strength examination of the influence of the different ways of layered polymerization processing on the mechanical properties of modern hybrid micro composite material with regards to the following quantities: compressive strength, strain to fracture, modulus of elasticity and work to fracture.
Composite material characterized with the low flow factors determining stress relief by viscous flow were the most promising ones [10].
The registered tendency is: the thinner the layer, the better the mechanical properties.
Increased temperature accelerates the polymerization of the composite and reduces the material viscosity, affects the process of composite material cross-linking what results in the increase of its strength properties.

In this study, the RVE model was developed in order to examine the mechanical properties (i.e.
Introduction Nickel-based superalloys exhibit exceptional mechanical properties at elevated temperatures due to the inclusion of elements such as chromium, iron, and niobium.
By analyzing the microstructure, researchers and engineers can gain a deeper understanding of the mechanical properties of the alloys.
In detail, as those factors decrease or increase the number of elements that a particular mesh applies, to understand the impact of the identified factors on the simulation result, a mesh sensitivity test was conducted.

Factors such as FS softening and insufficient joining, limited the fracture strength of the lap welds for small h values and these are presented and discussed.
Although the phenominon that the formation of a hook during FSLW could adversly affect the properties of lap welds is generally understood, a more quantitave relationship between the degree of hooking and FS parameters is yet to be developed.
Furthermore, the relative importance of the size of the hook and the degree of softening due to FS heat affecting the properties of age hardened Al alloy FSL welds has not been clear.
How processing conditions affect this h value and how this h value could affect fracture strength of the joint are the focus of the analysis below.
However, hooking is not the only factor affecting fracture strength, as various modes/locations of fracture were observed.

Results pointed out the fact that tilt angle played vital role in affecting the responses followed by feed and tool rotational speed.
Ramesh Babu et al [2] studied the effect of various welding parameters on mechanical properties during FSW of AA5083 and AA 6061.
By using mechanical clamps plates in position can be obtained and welding was performed.
The succeeding conclusions were drawn from this study · Tilt angle is the most momentous factor affecting the responses subsequently feed and tool rotational speed

Its running life is one of the main factors to influence the reliability [1].
Then the material is one of key factors to cause the above phenomenon for water lubrication bearings.
But plastic material exist some defects such as poor heat-resisting performance，water swelling performance，vulnerable to aging，mechanical properties and the size stability effected by temperature obviously.
Conclusions The material properties is in a large difference because of different working medium in thousands ways for water lubricating bearings.
Mechanical design.

But, it is necessary to understand that the simulation is based on idealization and averaging the physical and mechanical properties of the medium under study.
However real rock massive is heterogeneous and anisotropic, it has heterogeneity on physical and mechanical properties in different directions.
Hydrodynamic factors also have great significance.
That approach is confirmed by soil properties analysis: variation of properties doesn’t exceed 10-15% in one unit.
Furthermore there is influence of heterogeneity, caused by difference in physical and mechanical properties of soils.
