Abstract

It is shown that in tempered glass panels the edge stress and the thickness stress are closely related. Therefore the traditional edge stress measurement gives information also about the thickness stress and the surface stress. Thus for complete analysis of stresses near the edge of a glass panel only the edge stress measurement is needed.

Keywords

glass, photoelasticity, tempering stress, edge stress.
