Abstract
Tensile tests have been performed on specimens of Remco iron at strain rates from quasi-static to -2500/s and high-speed photography has been used to monitor the deformation of the specimen in tests at the highest rates. The DYNA 2D finite element code and the Johnson-Cook and Zerilli-Armstrong constitutive relations have been used to model the specimen behaviour in the impact test and the numerical predictions are compared with experimental measurements.
