OS1737 A Study on the Equation for Calculation of Stress in Taylor Impact Test by Using Pure Aluminum

Abstract

According to the method based on the Taylor impact test, stress can be calculated by theoretical formulae derived from momentum balance. Various kinds of formulae have already proposed and the optimum theoretical formula depends on material of specimen. In this study, to determine an optimum theoretical formula for annealed and unarmealed pure aluminum, stress-strain curve obtained by an impact compressive test based on the SHPB technique and the Taylor impact test are compared at a similar level of strain rate.
