Isostatic compaction of powders involves a suitably shaped elastomeric bag with loose powder, sealing the opening; immersing the bag in an oil (or a water) bath which is then pressurised. The initial geometry of the elastomeric bag (particularly the initial dimensions of the space occupied by the powder) is very important in ensuring a near net shape of the finished product. Currently, the elastomer and bag geometry are chosen either by a trial and error process or based on past experience.In this proposal, a micro-mechanics approach will be used to refine already established constitutive equations for modelling powder compaction processes. This refinement will include a treatment of strain induced anisotropy which is likely to be significant because of the finite deformation experienced by the powder particles and presence of the internal mandrel in the production of hollow cylindrical components. This will then be used to predict the pressed shape using finite element methods. Laboratory tests and full scale trials at Vesuvius UK (our industrial collaborator) will be used to validate developed models. We also wish to examine the influence process parameters during de-pressurisation on component integrity.
