Abstract
For overcoming the limitation of a low signal-to-noise ratio (SNR) in practical applications of luminescent photoelastic coating (LPC) method, a new LPC configuration applied in the LPC method is presented. Based on a brief introduction on the principle of molecular luminescence, the intensity formula for the new LPC is derived according to the theory of photoelasticity. Through the comparative analysis with the existing coating configurations (dual-layer coating and single-layer coating), the feasibility of this new LPC used in the LPC method for experimental strain analysis is proved theoretically, and the signal intensities of the LPC method can be increased by over two times.
