Abstract

The fracture behavior of a light cure composite resin under impact tensile loading 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 applied to the specimen was partitioned into three parts: the elastic energy left in the fractured specimen, the nonelastic energy due to viscoplastic deformation and the fracture energy for creating new surfaces. These energies were then determined and correlated with the fracture load. Energy release rates were also evaluated, and the results were discussed.
