Abstract
The purpose of this work is to enhance simulations of powder compaction by predicting the air entrapment mechanism. A previous numerical solution predicted the entrapped air pressure of a one dimensional compact. This work expands on this previous solution to produce a model that predicts the entrapped air pressure of a compact in two dimensions. By increasing the model to two dimensions, a more accurate estimate of entrapped air was produced. Additional insights on the mechanism of air entrapment were explored. The effects of compaction speed and the size of the punch-die gap on the entrapped air pressure were studied. Pre-compression was also modeled and the effects of the pre-compression relative density and the rest period were determined.
