The estimation of damping factors is of interest in most branches of engineering sciences.
It can also be seen from the data that the riveted joint loss factors are generally lower than those from the bolted joint.
The loss factors for the noncritical modes (3, 4, 5, 6, 8, 10) correlate well with the previous data shown in Fig. 5.
The general trend for the data is that the loss factors reduce for the higher modes.

Diffusive layers thickness At one paper it was shown that control on steel surface properties (carburized layer thickness, mechanical properties) is possible by changing processing conditions and composition of an electrolyte [7].
Thus, the composition of the electrolyte and the processing temperature are the factors influencing formation of diffusive layers.
Mechanical properties Martensite layer is obtained after PEN/C with hardening.
Dependencies of the strength properties vs electrolyte composition were not found.
The composition of the electrolyte and the treatment temperature are the factors influencing formation of diffusive layers.

However, more studies on behavior of concrete reinforced with fibers are needed because many factors affect on mechanical properties of fibers.

Usually, advanced mechanical properties can be traditionally achieved by alloying process, where some elements or chemical compounds are added to affect the chemical composition of the formed material.
Al A356 alloy has an outstanding castability, and mechanical and physical properties.
Usually A356 alloy mechanical properties enhanced by the alloying method [2–7] using master alloys, by heat treatment, or by applying ultrasound that affects the solidification process [8–10].
Mechanical properties of modified and non-modified A356 alloy by WC nanoparticles.
As the result, the alloys’ mechanical properties are improved.

It improves the surface and internal structure, enhances its mechanical and physical properties, and enables rapid and precise manufacturing of large-area, complex concave-convex or functionalized surface textures.
This is because mask-assisted electrochemical machining is influenced by multiple factors that affect the machining quality, including voltage, frequency, duty cycle, electrolyte, spacing, and others.
This is because if the height of the micro-columns is too low, it would not be able to generate sufficient depth of surface texture through cold pressing, thus affecting its oil storage functionality.
The orthogonal experimental factors and levels are shown in Table 3.

So the modified suspension parameter match can improve the full vehicle steady state steering characteristic without affecting other characteristics.

Nonetheless, the stringent requirements on the overall mechanical properties of the welded joint should be met [1].
Nuclear steam turbine low pressure rotors having a weight of 200 tons, which are designed to operate at the rate of 1500rpm (half-rate groups) in high-temperature water vapor for 60 years, are the key parts affecting the safety reliability of the power generator groups[2].
Due to the complicated welding heat process, inhomogeneity in compositions, microstructures and mechanical properties of the welded joint is inevitable[3].
Thus, the overall mechanical properties of the welded joint are critical for the reliability of rotor.
Among the existing researches on the overall mechanical properties of structures with long life, many concentrated on the fatigue crack initiation and fatigue crack propagation and corresponding affecting factors in materials with homogeneous microstructures[4].

In order to evaluate the metallurgical features on the weld beads/substrate interface a microstructural characterization was performed by using Scanning Electron Microscopy (SEM) and to evaluate the mechanical properties was conducted the wear test.
Weld pool geometry plays an important role in determining the mechanical and corrosion properties of the weld.
Thus the weld bead geometry plays an important role in determining the mechanical properties of the weld.

However, other important factors, such as yield stress, cannot be determined by the bending test due to the specimen’s thickness limitation.
Thus, measuring the properties of structures sized at the micron-scale can be answered most convincingly only through suitable experiment.
The theoretical stress concentration factors in the notched specimens are evaluated by the finite element analysis code ANSYS .

The effect of fibre type and fibre amount on physico-mechanical properties of slurry infiltrated fibre concrete (SIFCON) at both quasi-static and dynamic load was evaluated experimentally.
Mechanical properties of materials are different under impact loading compared to static loading [1].
It possesses excellent mechanical properties coupled with very good energy-absorption characteristics.
Two specimens reinforced with fibres with the same geometry but different tensile strength were used to assess the influence of the fibre mechanical properties on the impact behaviour of the whole composite.
