Modelling powder compaction and breakage of compacts Chenglong Shang Ph.D. Experimental and numerical simulation studies were carried out to enhance the understanding of the compaction behaviour of powder materials and to study the breakage behaviour of tablets after compaction. In order to simulate powder compaction and post compaction behaviour an appropriate constitutive model is required.

Chat Online· Powder compaction is a commonly used technique in numerous fields including the powder technology geologic pharmaceutical and thermal battery industries (Portal Euvrarde Tailhades and Rousset 1993). Uniaxial pressing consists of compacting the pressing powder contained in a rigid cavity by applying a pressure in a single axial direction with one or more rigid punches. The various pressing techniques differ in the movement of the basic mould elements top punch bottom punch and die. In a single action a uniaxial pressing pressure is applied through the top punch which enters the cavity holding the pressing powder. After the compacting the green piece and the top punch withdraw and the movement of the lower punch ejects the piece from the mould (Wagle Engel Liu and German 2000). The compaction mechanism of different material powders is different from each other and the formation of coherent compact is governed by a number of mechanisms (Mani Tabil and Sokhansanj 2004). The compaction of a given powder
Chat Online· In powder compaction simulation the numerical model must capture the physics of friction internal to the powder and at the die wall and the yielding of the powder bulk. In addition as densification takes place the material is expected to work-harden and the yield is consequently dependent on both hydrostatic and deviatoric stress states.
