Zusammenfassung:	An apparatus for testing a sheet of brittle material is disclosed. The apparatus can include a plurality of assemblies configured for selectively applying a 3-point bending load on an edge of the sheet of material in a test region of the apparatus, a detection mechanism that optically measures strain in the sheet of material in the region, and a processor that determines the stress in the sheet based on the measured strain by calculating the stress that would be required to produce the measured strain in the sheet of material.
