Stress Distribution in Ion Exchanged Glass PDF

Abstract

Experimental stress distribution for the forward ion exchange at two different temperatures 350 C and 500 C, obtained by successive slicing and photoelastic measurements, confirms the profiles calculated from the analogy to thermal stress theory and from finite element stress analysis. The measured profiles for the reverse field cases show much lower stresses than those predicted by the same theory. A theoretical analysis for the stress distribution calculated from the analogy to the thermal stress distribution and the effect of sample distortion due to slicing are briefly discussed.
