This analysis can point design parameter values of interest and the effect of factors on the properties.
Fiber length and amount are related to probability of fibers meeting that favors connection between channels, affecting porosity, density and permeability.
The Figure 8 show this factor’s influence in the S/N, of each assessed property, what the slope indicate the degree of factor’s influence on the property.
ANOVA verified which factors were statistically significant.
As the experiment aims higher permeability and mechanical performance associated with lower porosity and density, sample 2 showed better response of these properties, but its fluid dynamics property was compromised.

In this paper, temporary cavity is taken as the research object, and the main influence factors effecting temporary cavity are investigated.
Because the dynamic mechanical properties of living tissue were very complex, the study on the temporary cavity was very difficult [5].
In this paper, the influence factors effecting temporary cavity are obtained by analyzing the expansion process of temporary cavity.
From the above analyses, we can get some influencing factors impacting temporary cavity as follows: a0, ρp, v, c0, ρt, E, σD, pa, ζ, ψ.

Aluminum alloy heat treatment parameters are important factors for obtaining the best mechanical and electrical performance.
Table 2 gives the factors and their levels.
The higher hardness value needs to further improve re-aging temperature and re-aging time with a short time to obtain better mechanical properties.
The hardness results of the ANOVA, as shown in Table 5 indicate that pre-aging and re-aging time are the most significant heat treatment factors affecting hardness performance characteristics.
The electrical conductivity results of the ANOVA (Table 6) indicate that re-aging temperature and re-aging time are the most significant heat treatment factors affecting electrical conductivity performance characteristics.

Buildings suffered varied degree of attack from elevated temperature and thermal radiation, which leads to changes in physical, chemical and mechanical properties, might result in considerable damage to the buildings and their structure.
Numerical Simulation Model This paper uses Fire Dynamics Simulation (FDS) software to analyze thermal flow field of fire field, and then enter the temperature boundary conditions of simulation result in the thermal flow computation software PHOENICS to calculate temperature and mechanical properties inside the beam, in order to investigate variations in temperature and mechanical properties in the beam after undergoing a fire.
Factors of strength deduction of steel bars and concrete materials undergoing fire are diverse, of which, high temperature deriving from combustion in the fire field is the major parameter [7].
And the duration of influence from fire is also a factor that contributes to various changes in mechanical property.
The material properties of reinforced concrete inside the beam will change with increase of temperature.

The technologies development for obtaining nanoceramics represent a promising alternative for the production of implants and bone substitutes with improved biomechanical and biological properties.
This material presents an exceptionally high surface energy, which allows ceramic products fabrication with better mechanical properties without requiring the use of high processing temperatures, as in conventional methods.
The existing porosity in nanosized HA powder facilitates organic compounds adsorption like growth factors, which significantly improves the biological behavior and biocompatibility [5,6].
For this reason, it is very advantageous the development of procedures that conduced to HA analogous in properties to bone apatite.
Diverse factors have influence over the final properties and for this reason the processing conditions resulted very relevant.

Influence of the Form Factor on the Results of the Fracture Process Modeling under Uniaxial Tension Aleksandr O.
However, at this stage of development, engineering software modeling systems based on FEM make it possible to consider the behavior of objects only at the macrolevel, without taking into account the features of the micromechanism of destruction due to the high complexity regarding to all influencing factors.
Materials and Methods To obtain experimental data on the mechanical properties, 3 types of specimens of carbon steel (0.02% C) of a single melt were tested on a tensile testing machine: cylindrical (fivefold, diameter D = 5mm, cut from a thick-walled pipe), pipe fragments (diameter D = 25mm, wall thickness S = 3mm, total length - 350mm, base length - 180) and segments (cut from the specified pipe, width a = 8mm, thickness S = 3mm, total length - 150mm, base length - 50mm), prepared in accordance with GOST 1497.

This parameter is necessary for understanding the dependence of the screening properties of aerosol on the distance between the radiation source and the heated surface and is indicated in the graph (Figure 2).
This phenomenon can occur due to many factors and requires further study and experimental research.
Thus, it should be noted that the screening effect of aerosols is due to the synergistic action of several factors (Fig. 3).
Factors affecting the aerosol screening effect.
Accordingly, the screening effect will be created as a result of the synergistic sequential action of the above-mentioned factors.
