    Abstract

    Brittle fracture behavior of PMMA was studied using a high-speed extensometer. The single-edge-notched tensile specimens were fractured with a special loading jig so that it could split and fly away after the fracture. 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 fracutured 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 and external work, and the results were discussed.
