Abstract

The fracture behavior of a brittle polymer, polymethyl methacrylate (PMMA) resin, under static and impact tensile loadings was studied using single-edge-cracked specimens. The impact load and displacement were measured with a Piezo sensor and a high-speed extensometer, respectively. The load and displacement diagram, i.e., the external work Uex applied to the specimen was used to determine the elastic energy Ee and non-elastic energy En due to viscoelastic and plastic deformation, and the fracture energy Ef for creating new fracture surface As. The energy-release rate was then estimated using Gf = E f/As. The values of Ee, En, E f and Gf were correlated with the fracture loads, and the two results determined for the static and impact loadings were compared to study the effect of loading conditions.
