Abstract

This paper describes research that introduces computer-related technologies into the ceramic-making process, from designing to shaping. Ceramics have a unique problem, i.e., they undergo a major change during firing. Until now, predicting distortion has relied on experience, but this research examined distortion prediction techniques by applying finite element method (FEM) analysis technology. We investigated the conversion of the state of a virtual elastic material's distortion when gravity is applied to it into a firing distortion approximation model and confirmed that it is extremely convenient and an excellent prediction method. As a case study, a project that changed the original shape based on prediction techniques and drastically reduced the test firing was adopted. Based on the outcomes of a series of experiments, the trial production cycle has been drastically reduced, and even ceramic shapes that had been difficult to produce may be more easily realizable.
