Notes:
Dynamic visualization of stress distribution even due to a small deformation has been realized bycoating the surface of the test object of metal with a upgrade mechanoluminescence (ML) materialof SrAl2O4:Eu (SAO). In this paper we report the application of this ML sensing technique to stressconcentration analysis on an aluminium plate. And the comparison with a theoretical calculationdemonstrated that the ML intensity of SAO sensing film correlates linearly with von Mises stress onmetal surface and the observed real-time ML images quantitatively reflect stress concentration
