Generally, these models cannot evaluate the effect of the microscopic material size on the macroscopic mechanical property because they relate stress and strain between micro- and macroscopic scales.
However, the size of the pore may be one of important factors on the mechanical property of the material.
The relation was clearly affected by both of macroscopic and microscopic structure sizes.
The effect of the sizes of macroscopic and microscopic structures on the mechanical behavior of LDPE foam was investigated by computational simulation of bending of cantilever.

The alloys on systematic intermetallic phase matrix with aluminium fraction possess unique physicochemical and mechanical properties (e.g.
All these properties have been applied to the production of machine parts running in hard conditions (e.g. internal combustion turbine blades, engine exhaust valves, turbo blowers rotors) [2, 3].
Corrosion resistance of the object undergoing plastic treatment depends mainly on two factors: draft value and surface roughness.

The result shows that the width of the sealing surface and the contact stress altered with the change of structural parameters, which affected the sealing most.
So the leakage rate can be deduced as follows: (5) Considering the relationship between H and h is as follows: (6) where is the average stress on the sealing surface, is a sealing factor of the cone material.
So conclusion can be drawn that the seal property is the best when the cone angle is 24 degrees.

The physical and chemical properties of the samples were all taken from the area without local corrosion of B# samples.
The mechanical properties of the samples were tested according to the standard GB/T 228.1-2010, and the testing equipment was UTM 5305 material testing machine.

At the same time the hair moment of inertia is of order O(d2), negatively affecting the resonance frequency (i.e. bandwidth).
For the crickets the hair-sockets provide some torsional damping (R) by visco-elastic material properties (see [12] for such material properties in spider hair mechano sensors) whereas for the artificial hair-sensors torsional damping is caused by both material as well as squeeze film damping due to the small gap between the siliconnitride plates and the substrate.
However, with respect to damping the optimum damping factors still need to be identified.
Using optical read-out it was possible to improve the detection limit by a factor of ≈ 25 times [13].

Nonetheless, proper mineral or organic stabilizer dosages can reduce both issues by enhancing soil matrices' durability, mechanical properties, and hardening rate [6, 7].
The influence of liquid content is a critical factor that affects the printability of soil-cement matrices in 3D printing.
This strategy allows greater control of the matrix formulation regarding the pump working pressure since this depends on the matrix rheological properties and the pumping speed.
Although both height and width filaments are influenced by printing speed and water content, the most affected is the latter.
Future research works will evaluate the influence of cement addition on soil matrices' mechanical and rheological properties immediately after mixing and over time in the context of 3D printing.

These structural parameters have mainly positive influence on important mechanical properties of superalloys.
Solid solution provides fundamental strength characteristics of superalloys (tensile strength, fatigue properties, creep resistance, and hot-corrosion resistance) [6].
Unique properties of superalloys are close related to fraction of γ'-phase.
For example, coarse γ'-phase means decreasing of mechanical properties due to easier slip of dislocations.
Metallography is a powerful tool at fatigue failure mechanism description and provides information how microstructure is related to mechanical properties.

The asphalt mixture is a viscoelastic material, the main factors which affect its mechanical properties are loading and temperature.
Loading conditions are not easy to control, so temperature becomes the dominant factor to solve rutting.
Considering factors which like phase change temperature, phase change latent heat, thermal conductivity coefficient, volumetric change rate, volatility, boiling point and so on, myristic acid, palmitic acid, PEG 4000 are chosen and the thermal properties parameters are shown in Table 1.
Figure 16 indicates that the natural phase change fatigue of rutting specimen affect the results because of bad weather.
Conclusions When PCMA is at PCT or higher temperature range, the viscoelastic properties and corresponding road performance is deeply influenced, so the import mode is abandoned.

The exceeding of critical temperature is the root cause of degradation of useable properties of material.
For this reason the enhanced requirements regarding useable properties of basic engine parts must led to material with higher service parameters and its modern metallography and non-destructive diagnostics.
