抄録

Fracture energy is one of important parameters in estimating the resistance of crack propagation for refractories. However, the effect of the dimension of a test specimen on the fracture energy has not been sufficiently studied. In the present study, effective fracture energy γ_eff of chamotte refractory was evaluated using WOF (work of fracture) technique, in order to investigate the relationship between the fracture energy and specimen dimension. The γ_eff was significantly dependent on specimen dimension and notch length. Larger specimen dimension and shorter relative notch length made the γ_eff increased. For instance, the γ_eff of the large specimen was approximately three times as large as that of the small specimen. To evaluate accurate γ_eff for the refractory, a specimen with ligament longer than a given length was required. The ligament length was discussed in relation to the size of a frontal process zone.
