VERIFICATION OF MEASUREMENT OF DYNAMIC LOADING DURING THE TAYLOR ANVIL TEST

Abstract

The Taylor Anvil test is used to estimate dynamic behaviour of materials in an interval of strain rates of 102 to 104 s-1. The specimen is deformed due to impact on a rigid target instrumented with detectors. This measuring set provides an advantage in finding the forming force, which acted during the deformation. A Charpy hammer of nominal energy of 50J was used for the verification of dynamic loading induced by impact of a specimen. This measuring set is placed in the Laboratory of high strain rates at FME Brno, Institute of Manufacturing Technology, Department of Metal Forming and Plastics. The experiment arrangement allows comparing the results obtained independents by strain gauges and piezoelectric sensors.
