抄録

Single-edge-cracked specimens for tensile testing were fabricated by packing dental composite between two rectangular plates of polymethyl methacrylate (PMMA). To study the dynamic effect of brittle fracture and the nonelastic effect of the material, the specimens were pin-loaded with a special jig so that they could split and fly apart in the loading direction after fracture. The flying height and residual deformation of the split specimen were measured to estimate the elastic energy Ee and nonelastic energy En, respectively. The fracture energy Ef required to create a new fracture surface was obtained by subtracting Ee and En from the external work Uex applied to the specimen. The energy release rate Gf was also estimated using Ef.
