Multi-layered metal composites have received considerable attention due to their improved mechanical and physical properties.
Mechanical properties of processed material were evaluated using the uniaxial tensile test and shear punch test method (SPT).
Mechanical properties of Al / Ni / Cu were studied during different accumulated bonding cycles (ARB) [13].
SPT was carried out to analyze the effects of ARB process on mechanical properties of composite strips.
Also, the influence of SPD on the mechanical properties was investigated in uniaxial and shear loading.

This paper presents factors affecting the bond strength between GFRP reinforcement and concrete.
Reduction factors are higher for external exposure conditions such as bridge decks, beams, and columns.
Freeze-thaw cycles could cause significant reduction of the mechanical properties and glass-transition temperatures of the FRP specimens immersed in an aqueous environment.
It cannot be assumed similar responses for steel and GFRP bars due to their different mechanical and physical properties.

The results show that main cable stiffness not only has greater effect on the structure shape of long-span suspension bridge, it also has obvious impact on structure free vibration frequency, in addition, the torsion displacement of stiffening girder can be reduced effectively by adding central buckle, it improves structure bending and torsion stiffness significantly, central buckle also can improve free vibration frequency of structure and enhance structure dynamic stability, It shows that the influencing factors of structure static characteristics are restricted by rigidity of main cable, free vibration characteristics are affected by main cable and central buckle, they are not very sensitive to the variations of the parameters of suspender cable, stiffening girder and main tower.
In recent decades, with the development of economic, the standards of mechanical safety of bridge structure are raised.
Generally suspension bridge is flexible structure, it is composed of main cable, sling, stiffening girder, cable tower and anchorage, only the former four terms are taken into consideration while building the structure finite element (FE) model, the structure parameters, which corresponding to the four terms, will affect the structure mechanical characteristics.

They studied on a variety of geometrical and material properties and showed their effects on the frequency and the quality factor of resonance.
Frequencies, mode shapes and quality factors are calculated and illustrated.
Thermal and elastic properties of silicon are dependent to temperature.
The mechanical and thermal properties of silicon are depended to temperature so this damping should be investigated in constant temperature.

Ash particles input to the surface of soil leads to the decrease in their antierosion properties.
Physical and mechanical properties of soils and artiindustrates are determined by standard methods [6].
While violations affecting the AY and BM horizons, a number of coarse-silt fractions is increased in the grain texture composition and the content of the clay is significantly reduced.
Coalescence of the particles does not exceed 0.0002 kg cm-2 vs. in the brown soils this factor is 0.28 to 0.33 kg cm-2.

With the development of computer power and simulation methods, kinetic modeling becomes a powerful tool to clarify the key factors that affecting different phase distribution and guide the quantitative control of FGCC formation during sintering.
The simulation results of Ekroth et al.agreewell the experimental data, based on which the diffusion and thermodynamic properties of the alloy system are concluded to be two major factors that affect the gradient formation.
These interfaces can weaken the mechanical properties of FGCC.
Therefore, the carbon diffusion and its relating phase reaction processes was a key factor affecting the cobalt gradient in the WC-Co hardmetals.

Mechanical interlocking between untreated fibers and the matrix showed some increase in the mechanical properties of the untreated DPF-PP compared to the treated one.
In both cases, composites having 75% PP has better mechanical properties than the 50%PP composites.
The properties of composites mainly depend on three factors that are matrix, fibers and their interfacial bonding.
DPF/PP composite appeared to have better mechanical properties.

The study presented in this paper, aims at assessing how carbon nanotubes can affect cement composites and so the concrete, in terms of microstructure and physical-mechanical properties.
To evaluate the mechanical properties of the samples, destructive and non-destructive tests were carried out to obtain compressive strength, tensile strength by diametrical compression, dynamic modulus of elasticity as well as the determination of their deformation properties.
The study presented in this paper, aims at assessing how carbon nanotubes can affect cement composites, in terms of microstructure and physical-mechanical properties [1, 2].
Although the performance of these materials depends on several other factors, it provides a good indication of product quality.
