  • Method for detecting stresses
    Patent number: 5490426
    Abstract: A method for detecting stresses includes the steps of dispersing a fluorescent substance in a solid portion where stresses are to be detected, measuring fluorescence decay time of the fluorescent substance dispersed in the solid portion, and detecting stresses in the solid portion based on the measured fluorescence decay time. The method enables to non-destructively detect stresses in resin-molded products without impairing their mechanical properties.
