A Northern California failure analysis expert witness performs a glass failure analysis on broken tempered glass windows removed from a recently built Chicago Illinois high rise. Soon after construction windows in the high rise began to fail. Read Consulting which provides failure analysis services in Santa Rosa California was contracted to determine the cause of failure. A portion […]
Failure Analysis of Broken Tempered Glass Window
Failure analysis of tempered glass windows is normally impossible because the failed window falls apart into a large number of similar pieces, and locating the origin is impossible. However, there are cases when the window remains intact, and root cause failure analysis is possible. In this case the glass expert was able to preserve the […]
California Glass Expert Discusses Nickel Sulfide in Tempered Glass
In glass failure analysis one uses evidence such as the attached photograph to demonstrate that a nickel sulfide particle can initiate tempered glass failure. The NiS particle is at the center of expanding Wallner lines. The Wallner lines are used by the glass failure analysis expert to track the direction of the crack growth. In […]
Nickel Sulfide Particles in Tempered Glass
Glass failure analysis expert witness performs a failure analysis on a tempered glass window. The failure was initiated by a nickel sulfide, NiS particle. The glass failure analysis expert was able to retrieve both halves of the failure origin. One side of the failure origin contained the protruding NiS particle. On the other side of […]
Glass Expert Discusses Nickel Sulfide Spontaneous Failures
Glass failure analysis expert witness demonstrates that in the case of the spontaneous failure of tempered glass, the tempered glass failure is caused by the NiS particle. The failed glass door was taken apart to reveal the NiS particle. At this point the Wallner lines surrounding the NiS particle were located. The Wallner lines domonstrate […]
