Analysis of the Correlation Between the Results of Destructive and Nondestructive Methods of Monitoring the Strength of Witness Samples After Ion-Hardening

Resumo

Methods of monitoring the stress-strain state of strong elements for special glazing used in aircraft as well as for inclusion in transparent body armor are presented. Data obtained from monitoring of witness samples of chemically tempered glass by means of a scattered-light polariscope and a destructive, centrosymmetric, bending method are presented. On the basis of these data conclusions are drawn on whether or not nondestructive methods of monitoring can be used as indicators of the stress-strain state of a glass surface.
