Glass Failure Analysis of Tempered Glass
California Materials Failure Expert performs a Root Cause failure analysis of two tempered glass objects; a basketball backboard and a pickup truck rear window. Includes a discussion of Polarimeter surface stress measurements using a Strainoptics Grazing Angle Surface Polarimeter, GASP. Included is a detailed glass fracture analysis which includes determining the failure origin. This failure analysis study demonstrates how to analyze tempered glass.
California glass expert witness discusses crack travel directions during tempered glass failure. During tempered glass failure the glass sheet “self destructs” because the internal residual stresses are tensile and drive the failure. Essentially the glass failure results in the glass breaking into tiny cubes. This means that the crack is constantly changing directions. The California […]
Glass failure analysis expert witness performs a failure analysis on a hollow glass tube that failed due to internal pressure. The glass fracture initiated at a small bruise on the outer surface of the glass tube. The upper left 25X photomicrograph gives an overview of the failure. One can see that the glass fracture analysis […]
