These factors contributed to the increase in the shear strength of the riveted samples as the amount of pre-straining level increased.

The compressive stress-strain relations of the braided composites are not great affected by the geometrical sizes.
However, the mechanical properties of 3D braided composites are affected by many factors, such as the braid forms, manufacturing process, cutting edge conditions and fiber volume fraction etc.
The discrete mechanical properties of the braided composites, especially the strength of the material, can be attributed by the complex braid architecture of the braided composites.
The discrete mechanical properties and distribution characteristics of the composites are obtained.

Cooling rate, coiling temperature, and the open sequence of valve affect directly the final microstructures and mechanical properties of rolled products [8-11].
There are more factors affecting coiling temperature, in which strip velocity is strong timevariable, especially in accelerate rolling, time of different points through cooling zone is different.
The mechanical properties of cooled product reach or exceed the normative values.
Summary The cooling process on the runout table (ROT) has been modelled by taking into account the various factors that affect the temperature of the strip.
The mechanical properties of cooled product reach or exceed the normative values.

Surface preparation is potentially important to the mechanical and biomedical properties of NiTi shape memory alloys.
In recent years, surface preparation has attracted considerable attention due to its potentially important effect on properties of NiTi alloys [4-6].
There are many factors that affect fatigue life of NiTi wire.
The smoother surface has less slag, burrs, scratches or heat affected zones, and therefore less stress concentrations under exogenous action.
In addition, the hydrogen brittleness, caused by the hydrogen atoms absorbed in the course of the surface treatment, will severely deteriorate the mechanical properties.

This article presents the results of the influence of solar radiation (UV) on the strength properties of laminates with different types of reinforcement.
Introduction Aircraft parts, while in interaction with the natural environment, are exposed to the destructive influence of weather conditions as well as the factors that shape them together with local environmental changes.
UV radiation brings about the build-up of photooxidation mechanisms; therefore, it may be included in the group of atmospheric degradation factors.
Appearance of composite surface after impact loading: a) matrix cracks, b) area of delamination In the next phase, we specified mechanical properties of the newly prepared and damaged laminates.
These results may indicate a considerable impact of UV radiation on the strength properties of carbon fibres in the polymer matrix.

The technology is widely applied in the mechanical design and mechanical manufacturing field.
Suitable for mechanical product customization.
Whether accuracy and mechanical properties of metals can meet the requirements of industrial printing is still a problem.
Improve the processes and the structure of printing devices of 3D printing technology, to make mechanical properties of printed products better.
Through improving its printing device, Stepping speed, printing thickness and other factors, to achieve the purpose of increasing accuracy.

The approach presented in work of Tricoteaux [7] is similar to the one proposed above, whereas, it utilizes the Glinka-Molski model and the material properties for the heat affected zone, for the analysis of local strains and stresses.
As in practice, in the weld zone, we have to do with three different materials with different properties including: welds metal, heat affected zone, and base metal.
The basic mechanical properties of the base metal are given in table 2.
The system of fatigue and static testing of microobjects (MFS) enables determination of the material mechanical properties with the use of very small specimens and with the nanoscale accuracy.
This means that the analysis of the joint fatigue life based on the base material properties with the lack of other factors impact which might impair fatigue life in the weld zone (geometrical and structural notches), should provide conservative calculation results, especially for lower levels of local stress and strain.

The Role of Nano-SiO2 Addition in the Mechanical Properties of RHA Composite Cement Mortars A.
Incorporating nano-SiO2 into RHA mortars significantly improved the mechanical strength and water absorption properties of the products.
It has been observed that the extremely fine nano particles strongly affect their physical and chemical properties.
Some efforts on excellent mechanical properties and microstructure of cement composite with nano-SiO2 have been also reported [3].
The filler effect of nano-SiO2 is one of the important factors for the development of dense concrete/mortar with very high strength.

The rough surfaces and non-uniform thicknesses of chemically vapor-deposited (CVD) diamond films and substrates affect their industrial application.
Free abrasive mechanical polishing.
The mechanical polishing is only used to polish diamond flat film, and the factors that affect the efficiency of the polishing are the abrasive powders, rotate speed, positive pressure and polishing area of the polishing plate.

With metallization the plastic gains the properties like thermal conductivity, strength and hardness.
This work makes an extensive study to analyze the factors that are significantly affecting the wear nature of the deposited coating and to obtain an optimal combination of process parameters that results in a coating which adherant enough and has the lowest wear rate.
There are five basic controlling factors in like layer thickness, raster angle, air gap, part orientation, raster width in FDM route [16-18].
Factors which are significantly affecting the wear of the coating are raste angle, voltage and current.
