概要

The visualization technique we have developed is to coat the surfaces of structures with a paint that includes minute particles that emit light as a result of mechanical stimulation (elastico-luminescence, ESL). Thus, when the structures are subjected to force or vibration, the stress fields and danger levels of defects are made plainly visible at the same time as making the generation and location of defects, such as cracks that do not appear on the surfaces of structures, visible in real time due to luminecence intensity distribution on surfaces generated by stress. The positions and the danger levels of the cracks are detected simultaneously by using this technology, as invisible fatigue cracks and the undetectable stress concentrations of crack tips are made visual by coating metal plates with a paint that includes elastico-luminescent materials.
