Dynamic tensile testing for determining the stress-strain curve at different strain rate

A detailed discussion of high strain-rate tensile testing is presented. A c omparative analysis of different ways to measure stress and strain is made. The experimental stress-strain curves have been suitably interpreted to di stinguish between the real behaviour of the material and the influence of t he testing methodology itself A special two sections flat specimen design w as performed through FEA computer modelling, The mechanical Properties as f unction of strain rate were experimentally obtained and the measurement sys tem limitations were evaluated. The strain rate material law was simulated and a good correlation between experimental and simulated engineering stres s-strain curves was reached.
