FEM of ECDM Process on Semi Conducting Materials Lijo Paula*, P.V.
The scope of ECDM in micro machining of semiconducting materials is still found to be promising challenge for researchers.
Many researchers have carried out the modeling of ECDM for various engineering materials.
From the literature review it is found that very less work has been reported in FEM of ECDM in semi conducting materials.
An isothermal curve is generated with respect to melting point of the workpiece materials.

These materials are assembled by fusion with an energy source.

Introduction Nanosized materials are a field that takes a materials science-based approach to nanotechnology.
In recent years, computer simulation technology as an effective method has been widely used in materials science, especially the study of nanosized materials [2].
Materials sciences have turned from the traditional "trial and error" research into a quantitative science based on the basic principles.
Due to the unique properties of nanosized materials and broad application prospects, its structure and properties has become the focus of materials science, physics and chemistry, and other cross-disciplinary research [3].

Introduction Material Science plays a very important role in human history.
Therefore, the requirement of integration and sharing of computational resources and management of the material data is necessary for the researchers in material science.
The e-science platform is capable of providing the need for material scientists[1].
The safety evaluation for the pipe network of natural gas is a very typical application in material science.
