Introduction
The progress in the manufacture techniques has made it possible to produce mechanical structures and equipments of large scales.
At the dwell period, the PL intensity remained approximately the same, suggesting that PL intensity can be used as one of parameter sensing the deformation (stress) state of mechanical structures.
