Advantages and disadvantages of classical and some modified methods for SHPB data processing are discussed. Errors brought by using the classical methods under different experimental conditions are analyzed. Results show that the three-wave method which calculate the stress and strain with absolute time holds the best reliability and requires the least artificial correction, and the classical two-wave method is not a good choice for data processing in any circumstances. A simplified three-wave method is also proposed for some cases where three-wave measurement is impossible.
