By Visualizing the Deformation with Mechanoluminescent Particles, Additive Manufacturing Offers a Practical Alternative to Stress and Strain Simulation

The use of stress–strain analysis in structural design or mechanical components is critical for avoiding investigating failures. In the case complicated designs, mathematical full-field stress modeling produces imprecise predictions. Experimental can be used as a replacement modeling, but with currently available strain gauges, it cumbersome and impossible moving parts. Mechanoluminescent materials transform energy into visible light gauges to monitor strain/stress. Three-dimensional printing technology has made major advances terms additive manufacturing. this article, we describe method produce an ML 3D print. fabricated samples are precise versatile satisfy need easy non-destructible spatial analysis. A printed photopolymer sample SrAl2O4: Eu, Dy particle addition only final layers was tested, number optimized. It determined that optimal detection range 10 20 layers. opens possibility real-time evaluation complex uneven forces on parts, thus having good potential commercialization.
