Highlights on some reflections on characteristic angle, light intensity and their correlation to wavelength in three dimensional photoelastic media

摘要

The minimum normalised light intensity Inis introduced as a reliable characteristic parameter, in three dimensional photoelasticity, whose measurement is rather comfortable. Spectral, stress components, angle of divergence of the stress components, and material dependence of Inis investigated. Limits of a cited method are pointed out. Some misunderstandings that took place in Ref. (1) are highlighted. The basic concepts of two methods in integrated photoelasticity are compared.
