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 […]
Tempered Glass Failure: Nickel Sulfide Particle
California failure analysis expert examines glass door failure to determine the root cause of the failure. The subject tempered glass door failed spontaneously, and because the glass was verticle, the broken pane remained intact. Read Consulting failure analysis laboratory was able to obtain the origin and perform a root cause failure analysis. The attached 25X Nomarski photomicrograph […]
Chicago High Rise Window Failures
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 […]
Northern California Failure Expert Witness Describes Tubing Failure
An interesting failure of steel tubing was observed when 1 3/4″ diameter A513 Type 5 steel tubing was being bent in a tubing bender. In this case the tube was clamped into the bender in the wrong location. At this time the clamp bolt had made an indentation (nick) in the pipe surface. The pipe […]
Brass Plumbing Failure Analysis Stress Corrosion Cracking (SCC)
California failure analysis expert witness has analyzed numerous plumbing failures involving yellow brass (i.e. brass with more than 30% Zn in the alloy). The two major brass failure modes in yellow brass are dezincification and stress corrosion cracking. Above are two samples of stress corrosion cracking. Sress corrosion of yellow brass commonly involves the presence of ammonia along with the […]
