Therefore, following the procedure presented by Albuquerque et al. [3], domain integrals that come from these body forces can be transformed into boundary integrals.
As it can be seen, there is a good agreement between results computed in this work and the meshless local Petrov-Galerkin method proposed by Sladek et al. [5].

The size and content of SiC particles contained in the Al/SiCp composites are 30μm and 65% respectively.
Surface roughness (Ra) of Al/SiCp composites is shown in Fig. 2.
This phenomenon is expected in the machining of Al/SiCp composites.

El-Taybany et al. reported that the use of ultrasonic vibration reduces the moment compared to conventional milling [5].
During UAD of Al 7075-T6 alloy Amini et al. found that the drilling torque decreases with ultrasonic vibration, and increasing the spindle speed [6].Y.
Ahmed et al. found that UAD produces smoother surface than CD in alumina workpiece [7].

Total elongation (El) and uniform elongation (U-El) were approximately 30% and
17%, respectively.
These results mean that the TS-El balance is improved by adding Nb.
Park et al [6] disclosed that the ultra fine grained DP steel, with the ferrite grain size and martensite island size of ~0.8μm, showed higher strength and higher elongation than coarse grained DP steel.
The higher n-value and U-El in Nb-steel can be explained by this theory.
El of 5%Nb is nearly same as 0%Nb in spite of the higher strength.
