摘要：
In order to investigate the propagation of stress waves with phase transition under combined stress loading conditions, impact tension loading was applied on a pre-torqued thin walled tube made of NiTi alloy, which transformed its phase under stress loading. The coupling fast waves were observed, proving that the stress waves with phase transition under combined loading were coupling. The results show that the critical criterion for phase transition under combined stress is rate-nonsensitive. The signal of coupling slow waves was very small. A simulation was performed, which fit well with the experiment. The coupling slow waves could be distinguished. © 2017, Editorial Office of Journal of Vibration and Shock. All right reserved.
