✦ Synopsis

The #ying wedge is a dynamic tensile testing facility which is capable of generating strain rates from around 10 s\ up to in excess of 10 s. While the wedge concept was originally conceived as stop-gap method of making use of an existing facility, it was recognised that such an arrangement o!ered the advantage of simultaneously applied, true tensile loading at both ends of a test piece. The device has provided a valuable facility for conducting tests to explore the e!ects of strain rate, state-of-stress and temperature on the deformation and fracture of ductile materials and for the validation of DYNA codes for use in this area.
