This was interpreted as the modification of the residual stress field due to the mechanical indentation.
The way the defects are generated can have strong influence on the results, especially for shot peened samples, because it is a factor that can modify the residual stresses field introduced by this treatment.
This method slightly modifies the pre-existent residual stress field and the local mechanical properties of the material compared with mechanical work.
The smaller microholes where done with an indentation device, surely affecting the residual stresses field introduced by nitriding and shot peening treatment, while the larger defects are obtained by electroerosion much less invasive with respect of residual stresses.
The defect obtained by electro-erosion is more suitable for determining fatigue properties of nitrided and shot peened material.

The analysis of variance (ANOVA) was adapted to identify the most influential factors on the CNC end milling process.
The cutting speed is found to be the most significant factor affecting the surface roughness of work piece and tool wear in end milling process.
These superior properties plays an important role in the modern manufacturing industries, especially in aerospace ,automobiles, electronics and cutting tool industries.
Methods and Materials Surface roughness is one of the important factors to measure the quality of machine components.
Literature shows that [17-19] machining parameters like feed rate, cutting speed and axial depth of cut is the most dominant factors.

Considering the progress of crack evolution, the depth and the location of geometrical imperfection were critical factors in determining the mode of crack initiation and propagation.
Recently, concentrations were placed on the numerical study of mechanical behaviors of DP steels.
It turned out that initial geometrical imperfection severely affected the overall ductility and failure mode of the DP590 steel.

Electrospun fibrous scaffolds can be optimized in mechanical, chemical and degradative properties that can greatly influence their interaction with cells [4] and their high surface area and porosity provide attachment and migration of cells within the scaffold [5].
Carbon nanotubes (CNTs) have attracted considerable attention based on their excellent electrical and mechanical properties [18].
By incorporating CNTs to PPy, its electrical, mechanical and electrochemical properties can be improved, leading to increased actuation response and reduced actuation voltages [19, 20].
Similar effects of CNT incorporation on polyaniline fibers electrochemical properties was reported previously [37].
Increasing PPy and CNT addition decreased resistance and improved electrical properties of nanofibers.

Apart from these factors, which often have a strong emotional and economical charge, a very complex field of polymer materials science unfolds in the mapping of this problem, the main pillars of which are polymer blends, filled polymer systems, physical and mechanical property modifications with additives, reinforcing materials or technologies (e.g., multi-component molding, foaming) [5].
Due to the factors listed above, physical or otherwise mechanical recycling cannot be interpreted as a separate discipline but can be seen as a border science of several topics [6,7].
