| Abstract: | The limitation of industrial CT＇s inspection of SRM＇s defect was analyzed. The method of enlarging debonding clearance by low temperature freezing was put forward. The relation between debonding clearance and initial debonding length under the same temperature load was simulated by Ansys software. The conclusion that low temperature inspection could partially detect out the debonding which could not be detected out before freezing was drawn. |
| Keywords: | interlacial debonding low temperature inspection simulation |
