Details of the specimens is reported in the file. Residual stress measurement using a SCALP 5.0 on as-received and (in lab) annealed glass. Failure stress of as-received and (in lab) annealed glass, with its relative 60 sec equivalent stress. Weibull analysis of the above failure stress data. Evaluation of the above data, emphasizing on the strength gain due to healing, which is the scope of the paper.
