A compaction process of tiles consisting of two layers of powders with a rubber punch was discussed. The densification behaviors during compaction and sintering were simulated by the viscoplastic finite element method. In this method, both rubber punch and powder during the compaction were modeled as rigid porous materials. Using the rubber punch, the density distribution in the compact became more uniform, and thus the occurrence of fracture during the sintering could be prevented. The compaction process with a rubber punch is applicable to practical operations because of its easy applicability.
