In order to proof the program ' s effectiveness, we made some experiments on ly - 12a1 by shpb. in addition, based on the pochhammer - chree ' s theoretical solution about the stress wave propagation in infinite cylindrical bar, a numerical approach for analyzing dispersion in shpb experiments is developed
由於應力波在桿中傳播時存在彌散效應，在hopkinson桿實驗中，採用桿中某處的應變來代替桿與試件接觸端面處的應變，這必然會因為應力波的彌散效應給實驗結果帶來偏差。 -
