Abstract
Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.
