A modified TAYLOR-test in combination with numerical simulations - a new approach for the determination of model parameters under dynamic loads

Abstract
In the present paper a modified TAYLOR-impact-test, with VISAR technique, is presented. In comparison to a common TAYLOR-test analysis, the major advantage of the method used here is that we measure the dynamic material data from the velocity-time plot which is recorded continuously during the deformation process and not afterward from the distorted sample. Therefore additional advantages in this test method arise when it is combined with numerical simulations: With the measured velocity-time signal of the elastic wave propagations at rear side and the final shape of the specimen, enhanced validation calculations of the conducted test can be made. This can be used for a better evaluation and development of the model used in the numerical simulations.
