This test uses a standard universal testing machine to generate a release wave in a specimen under tension through the fracture of a mechanical fuse. Its main advantage is that both quasti-static and high rate stiffnesses can be obtained from a single specimen. This is thought to be particularly useful for materials with high specimen to specimen variability like bone. The presentation below shows a validation on PMMA.
