Abstract:The purpose of the research was to introduce a procedure to derive a powder compression parameter (EM A) representing particle yield stress using an effective medium equation and to compare the EM A parameter with the Heckel compression parameter (1/K).
Keywords:Powder compression   Compression parameter   Yield stress   Effective medium equation   Heckel equation
