Modelling powder compaction process for Zirconia powder under cold compaction.
Abstract:   (5120 Views)
Abstract-Nowadays utilization of simulation methods for prediction material behavior particularly in the development of powder metallurgy is increasing. The major importance of this method in powder metallurgy is reducing of costs and also, try and error of experiments. Furthermore Possibility to perform many experiments in normal conditions due to lack of facilities and also high cost of doing them, is not possible. In this paper the macromechanical and micromechanical models used for simulation of powder compaction process. Additionaly, the drucker-prager/cap model as the most complete and widely used model for ceramic powders are investigated. Contour of density distribution for zirconia sample with finite element method are obtained and the results compared with experimental results that obtain from other researchers and good agreement are observed. All results show the undeniable role of friction on the density distribution and stresses in the powder samples. Friction causes a density gradient and heterogeneity of density distribution in samples.
Keywords: Powder compaction process, Macromechanical model, Micromechanical model, Friction.
