| Abstract: | Under unidirectional tension, the near crack-tip strain field in superelastic Ni-51.8 at % Ti shape memory alloy which has two preparative edge crack is studied using digital speckle correlation method. By comparing specimen which were treated with different aging temperature, it is found that the different aging temperature greatly influences the near crack-tip strain field in superelasic NiTi alloy. |
