Today, sintering considers one of the significant processes that can be used in powder technology to produce a new solid product from powders using thermal energy. Many parameters can be successfully controlled by this process such as temperature, Particle size, process time, structure geometry, powder density, and powder composition. Study and analysis of the behavior of powder during the sintering process was carried out using finite element methods. The simulation provides two styles of discrete method and Qusi-static method. This research contributes to two types of processes in order to simulate the copper powder during the sintering process and to determine the variation by using contact and shrinkage ratios of powder behaviors. Finally, a comparison between the two styles of discrete element method explains how the selected parameters were impacted on the sintering process.

Composite sheets are relatively new materials used in different applications of sheet metals forming as it has better mechanical properties than the other employed engineering materials. Scientists of materials engineering try to connect between industrial applications and the characteristics of composite sheets to solve many of the industrial problems which have occurred. In addition, the composites sheets are used in complex designs for mechanical parts which used in space shuttles and submarines.In this study, an Sic particulatereinforced composite sheet was numerically simulated using finite element method to show the effect of silicon carbide particles arrangements on the design of Sicreinforced epoxy composite sheet.
