Context and motivations Thanks to its electrical properties, silicon carbide (SiC) is considered as the material of choice for high power and high temperature electronic devices while mechanical properties make it very attractive for Micro-Electro-Mechanical-Systems (MEMS) applications [1-3].
As a consequence, the impact of the thickness towards the mechanical properties of thin (< 1µm) 3C-SiC epilayers could be detrimental and seriously affect MEMS functioning.
This ratio is the leading property for any resonators, enabling to achieve higher resonant frequencies and better quality factors [13].
Influence of structural defect on the mechanical properties of 3C-SiC First, the mechanical properties of thin 3C-SiC layers (≤ 500nm) grown on silicon have been explored through the analysis of static and dynamic behavior of cantilevers.
Indeed, these authors suggested that the mechanical properties of 3C-SiC epilayers could be affected by the defect density.

The main factors affecting the freeze-thaw resistance of concrete had two aspects.
One aspect was some external factors, such as temperature, humidity and freeze-thaw cycles times.

This research is more focused on studying the effect of latex binder on the properties of TiO2 ceramic based material.
It has been found that the properties were influenced by the addition of binder.

It can be processed in exorbitant temperatures; because they constitute properties, such as great strength, sturdy corrosion resistance and exceptional thermal stability, S.Hanasaki [1].
The experiments were performed based on Design of Experiments (DOE), L9 orthogonal array with 3 factors and 3 levels.
It was observed that the feed and the cutting speed were significant cutting parameters for affecting the surface roughness and the feed and depth of cut were the significant cutting parameters for affecting the material removal rate.

For example, Cu2S, Cu5FeS4(bornite) had clarified better sliding and anti-wear properties in the dry friction test [7].
These sulfides showed better friction properties in the dry conditions [7].
In this study, the oil addition affects the friction properties.
Summary To investigate of solid lubricity in the base oil condition, synthesized sulfides were prepared and evaluated its tribological properties and surface states.
In the synthesized sulfides, bornite (Cu5FeS4) showed superior tribological properties, especially, under the extreme pressure condition.

The development of methods for calculation of underground structures that would fully consider the conditions of their creation and operation as well as actual properties of materials is one of crucial areas in structural mechanics.
The action of the temperature also changes physical and mechanical properties of the material (modulus of elasticity, thermal conductivity coefficient, etc.).
Further calculations take into account the impact of such factors as the rock fracturing and the temperature impact on the primary mechanical characteristic – modulus of elasticity – with the following function [2 – 5]: (1) Both problems were solved for a fixed time point t0, which is why such an elastic curve as E(r) as well as coefficients l(r), m(r), and k(r) related to it depend only on one coordinate - radius r.

The superior mechanical properties of PALFs is related to high content of alpha-cellulose and low microfibrillar angle (14°) [16].
Physical and mechanical properties of PALF are depicted in Table 3.
George et al. [17] reported that mechanical properties of composites are generally affected by the volume fraction of the added reinforcement, successful dispersion in the matrix, good fibre-matrix adhesion, fibre aspect ratio, fibre orientation as well as stress transfer efficiency of the interface.
The crystallinity may strongly influence mechanical properties of semicrystalline polymers.
The crystallinity may strongly influence mechanical properties of semicrystalline polymers.

Hence the mechanical property of composite with an open-hole has strongly attracted researcher interest.
Now the mechanical properties of composite under different environment have strongly attracted concerns of researches.
Tensile strength in low temperature environment is subjected to the combine influences of fiber and matrix properties, so it caused the tensile strength decreasing.
This is because the properties of matrix in wet-thermal environment will deteriorate on contact with humidity and high temperature, but fiber performance degradation is small.
As a general rule, tensile strength of composite is mainly depend on tensile properties of fiber, while carbon fiber is affected by wet-thermal aging slightly, so the tensile strength decline is not obvious.

It was found that samples quenched from 900°C have the highest mechanical properties.
Mechanical properties of joints obtained by different methods are compared.
In addition, differences in copper infiltration methods affected the mechanical properties of the material.
Copper-alloyed steels also showed [20] an increase in mechanical properties.
While the decomposition in steels with ~2 wt.% Cu affects the mechanical properties of the material – dispersion hardening occurs with a simultaneous decrease in impact toughness.
