Consolidation behavior of SiC powder under cold compaction

Abstract

Consolidation behavior of SiC powder was investigated under cold compaction. Experimental data were obtained from SiC powder under various confining pressure and axial stresses during triaxial compression. A special form of the Cap model was proposed from experimental data of SiC powder under triaxial compression. The proposed model was implemented into a finite element program ( abaqus) and the Cam–Clay model and the modified Drucker–Prager model were also employed to compare with experimental data. Density distributions were also measured indirectly and compared with finite element calculations. Finally, finite element calculations from various models were compared with experimental data for SiC powder under cold isostatic pressing and die compaction.
