Abstract


A detailed discussion of high strain-rate tensile testing is presented. A comparative analysis of different ways to measure stress and strain is made. The experimental stress-strain curves have been suitably interpreted to distinguish between the real behaviour of the material and the influence of the testing methodology itself. A special two sections flat specimen design was performed through FEA computer modelling. The mechanical properties as function of strain rate were experimentally obtained and the measurement system limitations were evaluated. The strain rate material law was simulated and a good correlation between experimental and simulated engineering stress-strain curves was reached.
