Abstract: | This paper describes an automatic measurement method for the stress analysis of a three-dirnensional photoelastic model having
the rotation of the principal stress by scattered-light photoelasticity using unpolarized light. The relative phase retardation
and the principal stress directions of a linear retarder for a distance in the solid model are expressed in terms of measurable
Stokes parameters. The method was used for measurements on a frozen stress sphere under diametral compression. |
