We have successfully demonstrated that the stress distribution of a metal substrate can be directly displayed by coating the surface of test objects with SrAl<sub>2</sub>O<sub>4</sub>:Eu (SAO), a strong mechanoluminescent material. An aluminum plate with the SAO sensing film was applied to experimental analysis of stress concentrations. This novel visualization technique can be applied to view stress concentration in various fields such as modeling, manufacturing and demonstration of industrial products.
