Verification of Efficiency of Theory Including Elasticity Effects of Punch and Plug

摘要

A mean green density-initial powder length relation is obtained by analyzing numerically a set of governing equations taking into account the elasticity of the punch and the plug. Firstly, the influence of their elasticity on the relation is examined based on the relations computed for eight different types of compaction. Secondly, two critical lengths, which were deduced in an earlier paper, are confirmed to exist in the curve representing the relation. Finally, the efficacy of this theory is verified by comparing the results with experimental data.
