Abstract

A mechanical test is described that can be used to measure the edge strength of annealed and heat-strengthened glass. The mechanical test apparatus stresses only one of the two edge-lines on the edge of a glass specimen. The testing concept employs the theory of unsymmetrical bending. The test device loads glass specimens in a manner that places tensile stresses on the tested edge-line while keeping the other edge-lines at zero stress or in compression. In annealed glass tests, the scored edge-line was found to be 20% weaker than the edge-line opposite the scored edge-line. Comparisons between the edge strengths of annealed and heat strengthened glass revealed that the mean edge strength of heat strengthened glass is larger than that of annealed glass by about 50%. © ASCE.
