Ultimate bearing capacity of statically-pressured pile pipe is affected by many factors, such as pile body, soil around pile and construction conditions.
Shallow soil layer will be excluded from the calculation of side friction, because of its small thickness, soft and uneven properties.
is weighted average of each physical-mechanical parameter of soil layer around pile.
The size of the correlation reflects the influence degree of vertical ultimate bearing capacity of single pile affected by various influencing factors.
Conclusions (1) Vertical ultimate bearing capacity of statically-pressured pipe pile is affected by many influencing factors and there exists higher complexity and nonlinearity among these factors as well as the ultimate bearing capacity and these factors.

In order to control the functional properties and to improve mechanical properties such as yield
strength and ultimate tensile strength, it is very necessary to introduce another hard phase into the
ductile matrix.
There are a lot of factors to affect the fracture toughness such as the volume fracture of reinforcement phase, microstructure and interface characteristic.
So the mechanism of reinforcement phase affecting the fracture toughness of 3DNMMC is not well understood.
There are other reasons for causing the deterioration of fracture properties.

Mechanical tests
Cylindrical solid and porous alloy samples were compressively tested to examine the mechanical properties.
The mechanical properties of the solid Ti4Ta4Sn alloy were measured by compressive tests.
Cytotoxicity of Ti4Sn4Sn Biocompatibility is a prime factor that affects the in vivo performance of an implant.
These mechanical properties are close to those of natural bone.

The reasons for this property scatter were investigated and traced back to different influencing factors.
Summarized, the test result is affected by a superposition of several influences.
The properties of the master heat are passed down to the specimen, while the manufacturing process adds further individualities.
It is self-evident, that manufacturers and users of the material are interested in those melts, whose properties are better than average.
Summary A weak correlation between the chemical composition and the mechanical properties could be detected.

Mechanical properties of sheet metals are the most important factors that affect sheet metal formability.
Chemical composition of the material, production methods and various treatments applied to the material during production are among the main factors that create differences in mechanical properties of sheet metals.
Basic mechanical properties of a material are determined by tensile tests.
In addition, mechanical properties of the materials were determined with tensile test.
It can be expected that all of the mechanical properties are close to the each other.

This new microstructure determines the local
material mechanical properties and influences the overall joint resistance.
The developed procedure allows one to successfully predict the most important factors needed for the process design.
As far as the mechanical properties of the material are regarded, tabular material flow stress data on the varying of the temperature and the strain rate were determined from literature data [10].
It is known that in FSW, the weld nugget is characterised by very good mechanical properties, sometimes even better than the parent material.

Thermokinetic factors affect the critical size and the speed of nuclei formation, their number and form.
Foundry iron "heredity" is determined by the following factors: 1.
Additional studies [15] showed that the level of mechanical and operational properties is at the optimum level.
It was found out that zinc contributes to ferritizing matrix, increases the content of graphite and coarsens it, which reduces mechanical properties to some extent.

The basic material property identified parallel to rolling direction (0o) and perpendicular to rolling direction (90o).
In conventional method, the strength design of steel structure is usually determined by using a safety factor where the value of the safety factor used in design phase will influence its weight[3,4,5,8].
In the Table 1, the specimen with thickness t = 0.6 mm shows that the tensile properties of base material tested under the load parallel to the rolling direction (0o) of specimen is 10 % higher than another one test load is perpendicular to rolling direction (90o).
Meanwhile, for specimen with t = 1.2 mm, the tensile properties of base material where the test load direction parallel to the rolling direction (0o) of specimen is quite similar (different 0.5%) with another one (perpendicular to rolling direction/ 90o).

Problem Statement
WPC manufacturers and consumer product designers need a better understanding of the mechanical properties of the composite and environmental effects on these properties [26,27].
Research is ongoing on the WPCs to improve their physical and mechanical properties [28], rheological properties [29], durability and morphology [30,31].
There are many factors affecting the stability of the extrusion process and the quality of the extruded products.
