Abstract:

Metal powder compaction is an important process in powder metallurgy (PM) industry, and it is widely applied in the manufacturing of key component in different fields. The numerical simulation based on the Finite Element Method (FEM) provides a flexible and efficient approach for the researchers of this process and its complicated mechanical behaviours. Die compaction of powder is a process which involves filling of dying with powder, compressing of the powder using rigid punches to form a dense, compact and ejection from the die. In this work, the modified Drunker-Prager Cap Model, a plasticity model for granular materials, is applied to represent the behaviour of metal powder during the compaction process. The model contains a number of material parameters which affect the accuracy of the Finite Element (FE) prediction. Methodology for parameter determination as described herein. The model has been validated by comparing the computed results with experimental results available in the literature survey. The predictive capability of the model has been demonstrated through the simulation of both compaction and ejection stages of the cylindrical specimen with various tooling motion. The tooling motion considering here include the top pressing and holding load features of a commercial pressing machine. Here ABAQUS solver was used to simulating the powder compaction process, and the results obtained from that are compared with the literature. Here we are going to consider material and geometrical nonlinearity of the powder compaction components.
