Paper Abstract

A strain rate calculation formula of split Hopkinson pressure bar (SHPB) test is derived from one-dimensional stress wave propagation theory. According to the test conditions and specimen size, the test strain rate can be calculated by the formula; and the strain rate limitative range of SHPB test is analyzed. 2D numerical simulation SHPB test of a bilinear strain-hardening material was carried out by LS-DYNA, and a series of SHPB tests of AA7055 aluminum alloy at different strain rates were designed by this strain rate calculation formula. The results indicate that this strain rate calculation formula is accurate and reliable, and the formula has some directing significance for SHPB testing program design.
