The 'flying wedge' is a dynamic tensile test rig for determining the fracture properties of ductile materials over a range of strain rates from 10~2- 10~4s~(-1). To accurately interpret the results from these tests, finite element models of the complete experiment as well as detailed models of the specimen subjected to different loading conditions are conducted. A new technique to carry out interrupted tensile testing at high strain rates on the flying wedge has been developed. Some typical results of the combined experimental and numerical technique are used to compare the predictions of different numerical ductile failure models.
