The ultra-fine grained (UFG) materials have been widely investigated due to their mechanical properties such as super high strength and super high plasticity.
It will greatly affect the extrusion process when processing parameter changed such as die geometrical parameters and friction condition.
Introduction The ultra-fine grained (UFG) materials have been widely investigated due to their mechanical properties such as super high strength and super high plasticity.
It will greatly affect the extrusion process when processing parameter changed such as die geometrical parameters and friction condition.
Friction condition is a disadvantageous factor during ECAP process and the die channel should be lubricated as good as possible in the pressing.

The principle of AFM is simple relatively, but there are more factors affecting the quality of the AFM [3].
A J Fletcher studied the thermal characteristics and rheological properties of polymers applied in the AFM and thought that the rheology of the medium plays an important role to the effect of the AFM [4].
Studies on various parameters affect the wear properties of the material with the help of finite element method and neural networks have been attempted by some researchers [3,7,8].
Known by the polymer material properties, the abrasive medium viscosity decreases with the shear rate increases, so, the “shear thinning” must be taken into account during the simulation.

In this regard, it is necessary to study the factors making possible to regulate the shrinkage and the solutions adhesion.
One of the important factors determining the adhesion strength is the cement-polymer composites shrinkage during hardening.
Rebinder [14] a cement stone elasticity high modulus leads to its low deformative properties, because it is associated with the predominance of hard and solid crystallization contacts in the cement stone structure.
It is known that modifying additives affect the majority of physical and physical-mechanical properties of cement systems.
The possibility of regulating the solidity, bearing capacity, deformative characteristics of cement-polymer materials, masonry, physical and mechanical properties of bricks due to the use of water-soluble polymers in the solutions composition is shown.

This involves mainly finite element method to simulate particular properties of designed structures or products.
The creation of a correct virtual prototype depends on many factors especially when modelling very complex structures.
One of the most important factors is sufficiently precise modelling of ties between structural parts, which influences the accuracy of results significantly, which was proved before.
Selection of connection types for combination of metals and alternative materials (e.g. fibre composites) is limited as some joints can damage fibres or matrix of composite material and so affect mechanical properties of whole structure.
The basic material properties of the composite pipe are shown in Tab. 1.

The aluminium-magnesium alloy AA5xxx series, which industry seeks due to its good mechanical properties, is also characterized by high springback values and by the Portevin-Le-Chatelier effect (PLC) [1].
These are the two main factors which limit the dissemination of AA5xxx series in the automotive industry.
Its composition and its mechanical properties are presented in Table 1 and Table 2, respectively.

Mechanical properties for common titanium alloys at 5.1-10.2 cm (2-4 in) diameter.
As such, the mechanical properties are dominated by the alpha phase.
This is supported by the mechanical properties in Table 2.

Introduction
The adaptability of polycarboxylate superplasticizer and cement is affected by many factors including type and properties of superplasticizer, composition and fineness of cement, type and dosage of mineral admixtures [1-4].
Many scholars [9-13] at home and abroad studied the influence of stone dust on workability, mechanical properties, and durability of concrete.
So the similar internal structure of mortar and concrete determines their macroscopic properties of approximation.
It also can better reflect the rheological properties of concrete.

The high strength steel is widely used in industry, and reinforcement study of high strength steel with LSP is of great significance to improve the fatigue life of mechanical properties.
Laser-generated shock waves in a confining medium have been used to improve the mechanical properties in the surface region of various metals such as aluminum, steel and copper.
This shock wave is purely mechanical in nature and results in significant changes in the microstructure and properties[8][9].
The main factors influencing effect of laser shock processing are wavelength, output energy, light spatial and temporal distribution characteristics, the pulse width.
The main factors that influence the effect of laser shock processing are pulse energy (E), pulse width(τ), spot diameter(D), the material and thickness of transparent overlay namely constrained layer(CL) and absorption layer(AL), size and shape of specimen material, mechanical properties of material, and laser shock overlapping rate[1][4].
