Comparison Between Dynamic Discrete Element Method and Static Discrete Element Method to Determine Neck Size Between Powders During Sintering Process

Sintering plays a significant role on powder technology which produces a new solid product from powders using thermal energy. There are many parameters effect on sintering process such as: Temperature, time, size of particles, geometrical structure of the powders, composition of the powder, density of the powders. Discrete element method is the best method to simulate the behaviour of powders during sintering process. There are two styles of discrete element method used in this report such as dynamic method and Qusi-static method. In this research will be compared of two types for DEM to simulate sintering process between two powders. In this paper, the sintering process between copper powders was simulated using discrete element method. The contact and shrinkage ratios were used to show the behaviour of copper powders during sintering process, and it was made a comparison between two styles of discrete element method. Some parameters used in the simulation to know the impact of these parameters on sintering process.
