Introduction Material removal phenomena are very important in many fabrication technology processes and the clear understanding of the fundamental actions of how workpiece materials are removed by a tool is critical in the production of miniaturized devices.
They used silicon as the workpiece and the tool materials, using the Tersoff potential function.

Experimental results explain “cutting wear” and “deformation wear” mechanisms are effective in cutting both the mild and the brittle structure materials with AWJ.
The pressure of the AWJ affects the surface roughness as the thickness of the material decreases.
Thus, the material cutting is achieved.

In this paper, a nondestructive technique is used as a tool to control cracks and microcracks in materials.
A simulation by a numerical approach such as the finite element method is employed to detect cracks in materials and eventually to study their propagation using a crucial parameter such as the stress intensity factor.
The nondestructive testing of materials became a tool impossible to circumvent for the improvement of quality (during the development) and of safety (at the time of the uniform), it relates to fields very diverse [3].
