Experimental based finite element simulation of cold isostatic pressing of metal powders
The present work addresses the various ingredients required for reliable finite element simulations of cold isostatic pressing (CIP) of metal powders. A plastic constitutive model for finite deformation is presented and implemented into an explicit finite element (FE) code. The FE implementation is verified so that numerical errors (both temporal and spatial errors) are kept under control. Ther...
متن کاملConstitutive Equation for Powder Compaction Incorporating Powder Charecteristics
The increasing importance of powdered materials fabrication has led to an increasing emphasis on the understanding of the powder behavior during compaction. During compaction, a powder mass undergoes densification owing to various mechanisms, i.e. sliding, rotation, deformation and/or fracturing of the constituent particles. These densification mechanisms are very dependent upon the powder char...
متن کاملInvestigation on the Consolidation Behaviour of Aluminium / nano - SiC Composite Powders Using Non - Linear Compaction Equation
The densification response of aluminium powder reinforced with nanometric SiC particles (50 nm) during uniaxial compaction was studied. To determine the effect of SiC nanoparticles on the compressibility of the matrix, monolithic Al powder was also examined. The effect of SiC nanoparticles on the densification mechanisms, i.e. particle rearrangement and plastic deformation, was analysed using m...
متن کاملHardness and Densification Behaviour of Copper and Bronze Powders Compacted with Uniaxial Die and Cold Isostatic Pressing Processes
A. Eksi, Faculty of Engineering and Architecture, Çukurova University, Adana, Turkey, M. K. Kulekci, Faculty of Technical Education, Mersin University, Tarsus, Turkey In this study hardness and densification behaviour of copper and bronze powders under wet bag cold isostatic and uniaxial die pressing processes are examined. In uniaxial pressing the specimens were compacted up to a pressure of 8...
متن کاملMechanical properties of powders for compaction and tableting: an overview.
This review provides an insight into mechanical properties that are critical to understanding powder processing for tableting. Various parameters that reflect these basic fundamental properties of powder and their evaluation by different techniques are described. Some recent examples in which these techniques are used in drug substance selection, formulation optimization or scale-up are also pr...
