It has been demonstrated that the infiltration process is affected by many factors: porosity of structural elements, wettability of their pore channels, fluid flowability of the infiltrating material, and other factors.
The infiltration process is influenced by many factors: the porosity of the elements of the product, the miscibility of their pore channels, the fluidity of the impregnating material and other factors.
The main properties of the briquette are shown in the Table 1.
The study showed a slight increase in the content of copper in the product elements and a decrease in their physical and mechanical properties in the case of two-stage sintering (Table 2).

Properties of Aluminum A356 and Al2O3 increased physical and mechanical properties of aluminum composite such as good wear resistance, low thermal coefficient, corrosion resistance, resistance to creep at high temperatures, and better fatigue resistance [2].
The interface bonding between the matrix and reinforcement are important factors that can affect the mechanical properties of the composite.
The presence of AlSi9 decreased ductility of Al2O3 and decreased mechanical properties of the composite [13].

In the process of removing wrinkles, possible related factors can be divided into two aspects.
The mechanical properties of fabrics that are associated with fabric movement include tensile and shear properties, bending, compression, surface characteristics, stiffness, fabric weight, and thickness [1].
Raja Zaoual obtained that fabric composition, weight, drape coefficient, fabric structure, warp and weft density and twist of fabric are the main factor affecting the performance of fabric wrinkle [3].
Therefore, the wrinkle recovery rate can be used to represent the comprehensive physical and mechanical properties of the fabric.

Furthermore, Heat Affected Zone (HAZ) tests are being introduced.
The complex correlations between the factors do not allow defining other properties (e. g. mechanical properties) through characteristics.
This chapter aims to present the properties of HAZ of (Q+T) high strength steel joints by the use of physical simulation, while the effect of welding parameters (t8.5/5 cooling times) on the different HAZ zones is also investigated.
Approaching to the lower limit, the risk of cold cracking increases, in case of long cooling times the reduction of toughness and strength properties can be expected.
- Using the Gleeble 3500 thermo-mechanical physical simulator the critical zones of S960QL HAZ can be reproduced.

This suggests that they might have a significant influence on the mechanical properties of ductile iron components.
This suggests that these stresses might have a significant influence on the mechanical properties of the material.
No temperature dependence is taken into account, as this quantity seems to affect the elastic properties of graphite only to a limited extent within the temperature range considered [16].

The interface of bolted joint commonly focuses on the research of non-linear damping and stiffness, which affect structural response.
Energy balancing method is developed to identify the dry-friction parameter and viscous damping factor.
Ren et al. [1] developed a general purpose technique based on multi-harmonic balance (MHB) to identify the properties of non-linear joints from dynamic test data.
Experiments Identifying the system parameter of bolted joint with non-linear factors need to obtain some equivalent input-output values according to Eq. (6) or (7).

Besides, the tribological properties of carbon fiber epoxy resin composites are mainly affected by ploughing of surface roughness at low temperature, while by surface debonding at high temperature.
Under the influence of heat, force and other environmental factors in space, the contact surface of the roller and guide rail pair in the pulley will produce thermal deformation and elastic deformation, which will lead to the change of matching clearance and friction of the roller and guide tribo-pair.

Factors such as elastic modulus and thickness of NCD film and elastic modulus of
interlayer which affect the shear stress distribution of NCD film on cemented carbide substrate were
investigated.
However, the variation of contact stress distribution usually accompanies the protection of NCD coating due to the difference in mechanical properties between the coating and the substrate [4].
Factors such as elastic modulus and thickness of NCD film and elastic modulus of interlayer which affect the distribution of the shear stress were investigated.
The mechanical properties of the models were presented in Table 1.
The interlayer is a thin layer formed in the initial period of CVD process which contained WC, graphite and diamond, of which the mechanical properties can be various.
