Summary on Grant Application Form
Cold isostatic pressing (CIP), where a rubber bag is filled with ceramic powder, sealed and subjected to hydrostatic pressure, is a method of forming ceramic compacts with near net-shape. A current industrial problem with the isostatic compaction of complex shapes is that the compact may be cracked after pressing. Current process modelling tools, whilst capable of modelling the compaction process, are unable to quantify the stress field during decompression. In this proposal these modelling tools will be improved through the combination of an experimental program to evaluate the mechanical behaviour of the system, and through the development of mathematical models. These will describe the role of the trapped air and the anisotropic mechanical response of the powder compact and will be integrated with a commercial finite element code in order to predict the detachment process in real components. The theoretical and numerical predictions will be compared with full-scale experimental results that will be obtained using facilities to be provided by one of our industrial collaborators.
