INTRODUCTION The complex properties, which are estimated on the basis of technology – cal and operational capability of the materials used in various sectors of the economy, physical and mechanical properties occupy a very important place [1].
Changing the formulation, manufacturing techniques and methods of formation – processing, the influence of external factors and determine the shelf – life state of a material, especially a polymer,and are reflected in its physical and mechanical characteristics.
These factors lead to micro-and-macroinhomogeneity of the materials of the processing technology of plastics in the product.
Thus, depending on the material properties, thermal and mechanical chemical treatment of parts value these characteristics are changing.

According to the review of the publications mentioned in the Introduction, factors such as the synthesis conditions, the volume percentage of ZrO2 -Si3N4, the orientation and geometry of the ceramics within the matrix, and other variables all impact the mechanical properties of the composites[17].
The presence of ZrO₂ influences the sintering behavior by stabilizing certain phases and improving toughness [31], affecting mechanical characteristics.
Other contributing factors to the strengthened mechanical characteristics include a decrease in crystallite size and an increase in lattice strain caused by including refractory particles [38].

Fillers play important roles in enhancing mechanical properties of NR latex films.
It was observed that tensile strength and tearing energy were affected by both factors listed.
Introduction It is well established that when reinforcing filler is added into rubber, the mechanical properties of the vulcanized rubber such as tensile strength, tear strength, crack-growth resistance and abrasion are enhanced [1].
However, when fillers are added into NR latex, the mechanical properties of the vulcanized filled NR latex film are lower than that of vulcanized unfilled NR latex.
Knotty tear phenomena observed on all samples tested showed that the samples prepared have good mechanical properties.

Energy, and especially its minimization, are factors which govern all physical processes.
Regions of mismatch within the solid, especially those associated with dislocations, interfere with dislocation cross-slip and thereby affect mechanical properties.

The scope of the work covers the development of the relationship between the chemical composition of surface-modified aluminium and its mechanical properties.
This article presents the impact of laser alloying with ZrO powder on the microstructure and mechanical properties of pure aluminium.
The desired mechanical properties, as well as the thickness of the oxide coating, depend mainly on the parameters of heat treatment via induction [11].
Optimizing the microstructure and improving the mechanical properties of the nano-structured zirconia coating also improves the technological plasticity [13].

This essay introduces the PHC pile of vertical bearing capacity, level of capacity, capacity and final pressure values, tensile properties, pile the stress mechanism, and the factors that influence bearing capacity, then the useful suggestions of how to design and construct are given.
Currently there are two types of commonly used formula: First, the physical and mechanical properties of soil and a large number of test piles is based on information established by statistical analysis and pile tip resistance and the relationship between indicators of soil types; the other is soil mechanical properties, such as the Land of the standard penetration blow count based.
Also, care should: (1) when the final pressure should be based on the number of consecutive re-pressing the pile length and geological conditions and other factors to determine, generally not more than three times.

Conclusion This paper summarizes the characteristics and bearing capacity of pipe stress analysis, the factors affecting pile bearing capacity and to improve the bearing capacity of pile method.

This study involved the fabrication of the Al 2024 wall and the mechanical properties, deposition rate, and microstructural properties were analyzed.
This study proposed a unique strategy to increase the deposition rate without affecting the mechanical characteristics and bead geometrics due to high heat input.
This reduction was the primary criterion to eliminate the defects due to increased heat input which affect the bead geometry and mechanical properties.
The welding current was identified as an important variable affecting the strength of the welded joints.
The input factors considered are CW, TSN, and DNW and the output parameter is DR.

Based on Bishop Model, the equilibrium equation is established to evaluate the slope instability risk accounting for the uncertainties arising from soil properties and water level.
It is difficult to reflect the stochastic influences by using deterministic approaches because uncertain factors always are stochastic.
Uncertainties in soil properties can rise from inhere spatial variability in the properties and random testing errors in their measurements.
