As a result of a window failure analysis performed by a failure analysis expert, several observations were made with respect to metal clad wood windows. The perception is that these windows are almost maintenance free. The outside metal cladding does not need painting, and the wood layer is inside, so it requires minimal maintenance. Numerous […]
Coffee Pot Failure Analysis
A failure analysis was performed on a glass coffee press. In this case the glass coffee pot is a 0.085″ thick borosilicate glass 3.7″ diameter cylinder that is 7″ high. It had received a blow on the top rim, and it broke into approximately 10 pieces. Because the pot is a cylinder, the blow from […]
Glass Failure Analysis: Windshield
A failure analysis was performed on a light rail windshield failure. In this there was a pop and the operator was showered with glass. The glass failure analysis expert witness determined that there were two leads to the windshield defogger that were in proximity and because they were improperly wired, arcing occurred between them. The […]
Cast Iron Metal Fatigue Failure
California failure analysis expert performs a failure analysis on a failed cast iron “latch lever” from a wood stove. This failure initiated as a fatigue crack at a casting defect. It progressed as a fatigue crack through most of the thickness until the final overload failure. Upper left is a photograph of the backside of […]
Failure Analysis: “Exploding” Coffee Pot
California failure analysis expert was presented with the claim that a coffee pot had “exploded” when replaced on the coffee warmer in a convenience store.First of all, there is no “stored” energy to cause an explosion. The coffee is not under pressure, and the pot is made from annealed borosilicate glass. In addition, the broken […]
