Abstract

Taylor anvil test is one of the dynamic test method used to determine the dependences of strain rate, strain and temperature on flow stress. This method can be used to determine the stress and strain at any point in the specimen at different temperatures and strain rates. The paper deals with the description of the Taylor anvil test experiment for G3Si1 welding wire. The experiment was carried out in the laboratory of high strain rates at the Faculty of Mechanical Engineering of Brno University of Technology. ANSYS Explicit dynamics software was used to simulate the material behaviour during the test. The Johnson-Cook constitutive relation was used to describe the material behaviour. The simulation results were compared with the experiment.
