Determination of the Material Characteristics by Means of a High Speed Tensile Test - Experiments and Simulations

ABSTRACTThree high speed tensile tests of the aluminum alloy AlMg3 and finite element (FE) simula-tions of these tests were performed. The strain rate dependency parameters for the Cowper-Symonds material model, which minimize the difference between measured and simulated displacement results, were deter-mined. The verification of the determined parameters by means of strain distribution comparisons between an additional experiment and its simulation revealed the necessity for further consideration of the parameters.
