Glass fracture and changes in bending load were investigated by the quasi-static loading method which is characterized by holding a fixed time at each displacement level and incrementally applying displacement. Holding time at each step was 60 s and the incremental displacement was 0.02 mm as the load condition. Ordinary soda-lime-silicate float glass of 50 × 10 × 4 mm was used as the specimen. The glass fracture occurred as the bending load decreased with time, which might be explained using the occurrence of time-dependent fracture and function as a viscoelastic property even at room temperature. Fracture properties of alumina ceramics have the possibility to be closer to float glass than silicon carbide which is called general ceramics.

Tensile stiffness of interfacial layered rock is the basis of studying the law of interlaminar propagation of hydraulic cracks. We used similar materials to make simulated specimens of sand-mud layered rock with prefabricated cracks, and used the digital image correlation (DIC) technique together with the three-point bending (TPB) test to obtain the strain field near the prefabricated crack tip in tensile state. Combined with the tensile stress in the corresponding area calculated by the load of the tester, the tensile stress-displacement curve at the interface of layered rock is obtained, and the tensile stiffness and interfacial fracture law at the interface of layered rock is calculated by the curve. The results show that in the process of tensile failure, before reaching its peak value, the interfacial tension stress of layered rock has a linear elastic deformation stage followed by a short hardening stage. Upon reaching the peak value, it is accompanied by interfacial failure and macro-cracks, and then the load decreases and enters the softening stage, which results in the complete destruction of the interface. The tensile stiffness values of layered rock with different sizes vary greatly, which indicates that the interfacial tensile stiffness values are sensitive to the specimen size and have a size effect. The results are of great significance to the study of the law of hydraulic fracture propagation in the interface of layered rock.
