This paper describes results from Taylor impact experiments on specimens cut from a Ti-6Al-4V plate. High-speed photography and a mirror arrangement are used to obtain images of the specimen from three views. The positions of the edges of the specimen in these images are then used to fully reconstruct the specimen surface in 3D, allowing the real-time anisotropic deformation of the specimen to be studied. Further to this, the traditional anvil used in Taylor impact experiments has been replaced with an instrumented target bar, which enables the force at the end of the specimen to be calculated over the duration of the experiment. The results from these Taylor impact experiments are compared to Finite Element simulations using an anisotropic material model.
