Test Evaluation and Computational Modeling Applicability for Compression Moldability of Inert Explosive

Jin Sung Lee, Jung Su Park

Abstract

Using an inert explosive powder, molding experiments were carried out. And a computational model analysis was performed to predict moldability behaviour of an inert explosive powder. In order to analysis the Shima-Oyane yield model to predict the behaviour of the densification for inert explosive powder, using an inert explosive powder was carried out moldability tests on the pressure, could be obtained volumetric strain on the pressure, relative density and so on. Based on the results of the curve fitting, it could be derived the parameters for the yield function of the cap with the critical state. Finite element analysis for both double action pressing and isostatic pressing process of the two yield models were performed. And changes in relative density and densification behaviour of an inert explosive powder were analysed. In addition, it investigated the distribution of the relative density or volumetric strain caused by the overall and local variations. It was founded the maximum stress and position etc. under working pressure of inert explosive powder.
