Abstract

The fracture behaviour of ceramic refractory plates was investigated starting in terms of frequency and type of fracture. The plates investigated were used in industrial practice as a support for porcelain whitewares. To fully understand the fracture nucleation and propagation, a numerical model was adopted. This approach relies on the finite element method for the investigation of stresses arising upon thermal loading due to firing cycles. Moreover, a fracture criterion suitable for brittle materials such as ceramic refractory plates was used in conjunction with the finite element analysis in order to determine fracture initiation. In particular, two similar modes of fracture were chosen corresponding to a crack running from one boundary to the opposite one and starting from a critical point. 14 refs.
