The result of a failure analysis, a glass expert presents several views of a 180µ diameter origin (nickel sulfide particle) of a failed tempered glass door. The upper left photomicrograph is taken with a low power optical microscope and it includes the NiS particle and the initial Wallner lines. Upper right and lower left are […]
Glass Failure Analysis of Laminated and Tempered GLass
Glass failure analysis was performed by a failure analysis expert on a large laminated window of which one layer was tempered glass. The tempered half of the lamination failed. The other half of the window held the system together, and this allowed a failure analysis to be performed. The upper left photo is an […]
Failure Analysis Expert shows Nickel Sulfide Particle
Failure analysis expert observed a nickel sulfide particle using Nomarski optics. The various colors show different elevations of the surface around the particle. This particle was at the origin of a failed tempered glass door. This is an interesting result of a glass failure analysis performed on the door. […]
Glass Expert Analyzes Wine Bottle Defect
A glass expert was asked to examine poor quality bottles received by a winery. The issue was whether this product defect would significantly lower the strength of the bottle and would present a product liability problem. The photo on the upper left is a photograph of the manufacturing defect. It is a 4 inch horizontal […]
Failure Analysis Expert Performs Glass Failure Analysis
Glass expert performs a failure analysis on a failed tempered glass door. The spontaneous glass failure was analyzed to determine the cause of failure. This was one of several doors that failed spontaneously on a new high rise. Fortunately, the door did not fall apart; thus, the failure origin could be preserved. The upper left […]
