The application of ceramic materials in engineering structure has increased significantly for their outstanding hardness and yield stress under compressive loading. However, fracture behavior of ceramic materials is closely related to microcracking. Continuum damage mechanics is considered as a powerful theoretical framework. It is fairly difficult to obtain analytically as well as experimentally evolution equations for ceramic with microcracking. In the present study, an effective computational procedure is employed in a dynamic fracture analysis of ceramic materials with microcracking. The computational analysis is carried out for simulation of fracture experiment using notched specimens. This procedure can be used for better interpretation of experimental data as well as fracture simulations of complex structural models. Additionally, ceramic specimen is applied to the finite element analysis of microcracking near the microcrack-tip in a tensile stress field. The simulations were not only consistent with the experiments, but also revealed a possible damage mechanism which helps to explain the experimental data.
