| 摘 要： | 分析了ＳＨＰＢ试验中导致试件早期应力不均匀性的主要因素，指出试件中应力波的波速是与试件材料的应力应变曲线耦合在一起的，提出了考虑应力不均匀性的解耦方法，这种解耦方法具有普遍性，可广泛用于ＳＨＰＢ实验数据处理。

| Abstract: | In this paper,the main factors that lead to the stress nonuniformity in the early stage of specimen deformation in SHPB test are analysed.It is pointed out that the stress wave velocity in the specimen is coupled with stress strain curve of the specimen.The coupling solved method about the stress nonuniformity is put forward.This method is of universal significance and can be applied widely for SHPB experimental data processing. |
