Research of Stress Detection Based on Mechanoluminescence

Abstract

Stress and stress concentration are one of the main factors of invalidating load-bearing structural members. Stress detection becomes an important part of industrial production. Mechanoluminescent (ML), which is produced by mechanical stimulation acting on materials, has been suggested to use in stress detection. This work focuses on the development and mechanism of ML, concludes with the applications of ML on the stress measurement, and discusses the specific challenges to the future directions of ML.
