Photoelastic Express Diagnostics of the Surface Stresses in Rod Elements with Radial Refractive Index Gradient

Abstract

The paper presents the derivation of the equation for express determination of surface residual stresses in GRIN glass rods with axially symmetrical refractive index distribution n(r). At n(r)=const, it becomes the V.L. Indenbom’s relation for quenched glass cylinders.
