A California failure analysis expert has been testing the strength of beer bottles by causing them to fail from pressure overload. In all cases the origin always had a mirror region at the origin. The presence of the mirror region indicates that the crack initially grows slowly. Theoretically, the mist hackle indicates that the crack velocity has […]
Failure Analysis Expert Examines a Broken Champagne Bottle
A California failure analysis expert witness was asked to perform a glass failure analysis on a champagne bottle that had failed “spotnaeously”. Because champagne is under pressure and in glass, there are warnings not to use a cork screw to remove the cork. However, there are cases where the cork is stuck and people will […]
Glass Fracture, Califirnia Glass ExpertPerforms Bottle Failure Analysis
California failure analysis expert witness was asked to perform a detailed failure analysis of a broken wine bottle. Glass fractography was used to determine the root cause failure mode. The failure originated at damage caused by the prop on the cork screw. The fact that there were two damage sites on opposite sides of the […]
Failure Analysis Expert Examines Bottle Failure
Glass failure analysis expert witness prepared numerous bottle failures of “off the shelf” 12 oz beer bottles by over-pressuring them with a hydraulic pump. These tests were needed to generate bottle failures of a known origin in order to examine the crack patterns, the fracture surfaces, and the failure origins. Numerous bottles were broken, and […]
High Pressure Bottle Failure Analysis Tests
Glass failure analysis requires looking at failed bottles and determining the cause of failure. The failure analysis procedure includes carefully examining the crack pattern and the failure origin. It also helps to have failures with known causes to confirm the conclusions. In this case, bottles were purposely broken using hydraulic pressure. Their performance was documented […]
