Three-dimensional, inelastic response of single-edge notch bend specimens subjected to impact loading

Many significant problems in fracture mechanics of ductile metals involve surface breaking defects (cracks) located in structures that are subjected to short-duration loading caused by impact or blast. When the severity of impact loads is sufficient to produce large inelastic deformations, the assessment of crack-tip conditions must include the effects of plasticity, strain rate and inertia. This research examines the interaction of impact loading, inelastic material deformation and crack geometry with the goal of improving procedures for the engineering assessment of flaws located in critical structures. The work focuses on the bending-type test specimen employed to measure the inherent fracture toughness of a material. A thorough understanding of the test specimen behavior is a prerequisite to the application of measured material properties in structural applications.
