FOS usually defined above 1 to compensate the actual characteristics and uncertainty condition of the material used including other external factors[5].
Properties of the material used is 1023 Carbon Steel Sheet (SS).
The result shows that the top cover thickness is the most affecting factor of the safety factor because the load is applied directly on the surface.
However, the base is not affecting the design much due to the design flange and shape including the well force distribution.

The concrete conglomerate properties change over time and depend on a number of factors.
It is known that many factors affect the stress field heterogeneity.
Its properties change over time and depend on humidity, ambient temperature, and other factors.
Thus, existing proposals come down to the fact that the elastic modulus is mainly affected by the properties and relative content of the aggregate, and the composition and properties of cement stone do not have a noticeable effect.

In any welding process the input parameters have an influence on joint’s mechanical properties.
By varying the input process parameters combinations, the output would be different welded joints with significant variations in their mechanical properties.
Competent, experienced engineering and supervision are required to successfully obtain the mechanical properties that can be realized with the CSEF steels.
All the other factors were controlled and maintained per requirements and the welding was finalized as per the procedure.
PWHT at temperature of 760°C for 2 hours has good influence on mechanical properties because the hardness decreases and turns out to be uniformly distributed.

Titanium has attractive mechanical properties [1].
The experimental data of mechanical titanium properties, which are necessary in numerical simulations, were given.
The increase of temperature in the heat affected zone (HAZ) during the welding process causes changes in material’s mechanical properties.
In [6] different methods for the measurement of TWB mechanical properties within a heat affected zone were suggested.
The assumed mechanical properties of Grade 2 and Grade 5 titanium as a function of temperature are shown in Table 1.

Introduction Casing failure of thermal recovery wells is affected by many factors, such as material characteristics of casing, strata characteristics, faults movement, and so on.
In thermal recovery wells, casing failure is affected by strata and geological condition [12].
Stress and strain of casing are analyzed, and influences of some factors on thermal-mechanical results are investigated.
Modeling for Thermal mechanical coupling Casing failure is affected by casing material, fluid behavior, strata condition, construction quality and so on.
Therefore, strains are affected by both force action and steam injection times.

These results highlight that the mechanical performances of the investigated blends are affected by the viscosity ratio and the tacticity of the two polymer melts more than by the individual polymer properties.
Summary In this work, the blending of two commercial types of PLA with PBAT showed that the mechanical performances of these blends were affected by the viscosity ratio and by the tacticity of the polymers, more than by the individual component properties.
Both these factors led to a finer morphology and higher interfacial adhesion between the homo-phases that was traduced in the better mechanical performance of the resulting blend.

The factors of acid concentration, temperature and time affect the mechnical behavior of the fibers of nylon 56 ,nylon6 and nylon 66.
Inappropriate acidic conditions may cause changes in the structure of fibers, damage the fibers, and poor the mechanical properties.
The influence of different factors on fracture strength of nylon fibers is shown in Fig. 1~3.
Combined with fig.1~3, we can indicate that temperature, processing time and content of acetic acid are all variables that affect mechanical properties of nylon fibers, and temperature and alkali concentration have larger effect on the fiber strength when compared with effect of processing time.
Conclusion Temperature and concentration play the main role on the acid resistant among the factors that influence acid resistant of nylon fibers: temperature, time, and concentration of acid.

Moreover, studying of the mechanical properties of materials is important for all natural fibres composite materials.
The various parameters affecting mechanical properties also need to be studied to analyse the natural fibre composites materials.
The natural fibre composites were characterized through mechanical tests: compressive and tensile properties.
