Debonding detecting method and debonding detecting device
A debonding detecting method detects debonding of an adhering portion at which an adhering object adheres to an adherend. An optical fiber sensor is provided on the adherend adjacent to the adhering object. A longitudinal direction of the optical fiber sensor is along a direction in which the adheri...

| description | A debonding detecting method detects debonding of an adhering portion at which an adhering object adheres to an adherend. An optical fiber sensor is provided on the adherend adjacent to the adhering object. A longitudinal direction of the optical fiber sensor is along a direction in which the adhering object extends. Reference strain data of a strain measured by the optical fiber sensor is prepared in advance when a load is applied to the adherend in a reference state in which debonding of the adhering portion does not occur. The debonding detecting method includes: applying a load to the adherend; measuring a strain of the adherend by the optical fiber sensor; and the determining presence or absence of debonding based on comparison result obtained by comparing measured strain data measured in the measuring and the reference strain data. |
