Failure analysis of wine bottle reveals a
manufacturing defect. In this case the root cause is a piece of un-melted glass.
Manufacturing Engineer analyses failures of heated automobile rear view mirrors.
During the start of the scribe and break process, the scribe tool would crush
the glass. This crush initiated the thermal stress failure.
Summary: Glass Failure Expert analysis broken glass cookware. This is a Pyrex
pie plate that broke during use
Summary: California Plastic Expert Discusses failure of plastic lawn chair.
Summary: California Glass Failure Expert Discusses surface stresses encountered with
tempered and heat strengthened glass. Root cause failure analysis of a tempered
glass basketball backboard. Included are the fracture origin and a discussion of
the effect of surface stresses on tempered glass fracture.
Summary: California metallurgist discusses Metal Failure Analysis of a surgical implant ; Product liability study and Failure analysis of a 316 stainless steel surgical implant. Includes
scanning electron microscope (SEM) analysis of the fatigue failure. Example of
product defect analysis.
Summary: California ceramic and Porcelain failure expert performs a product defect analysis which includes failure analysis of a porcelain toilet water tank. Included
are porcelain ceramic
failure analysis and evidence of prior leaking. Results indicate that there was
no product defect or manufacturing defect present
Summary: California Intellectual Property and Patent expert discusses an Intellectual property case that includes a discussion of
a trade secrets and the measurement techniques that are used to perform
reverse engineering. Included are coordinate measuring machine, materials
surface analysis and various polymer analysis techniques.
Summary: California Packaging expert discusses a food packaging and product liability case which includes a root cause analysis of the source of steel filing contaminant
found in tomato sauce. Detection methods include Fourier Transform Infrared
Analysis, FTIR, to identify the polymer can liner and Energy dispersive X-ray
analysis, EDAX, of the steel filing to determine its composition.
Summary: California Glass fracture expert discusses a product liability case with a detailed failure analysis of a broken jar. Includes a root cause
determination and detection of the failure origin. Includes analysis of damage
to the steel lid of the jar. This failure was the result of impact damage to the
jar. There was no product defect present.
Summary: California Glass expert performs a root cause failure analysis of a broken wine bottle. Included is an
analysis of damage caused by the cork screw, crack initiation and crack
propagation.
Summary: California Materials failure analysis expert performs a Root Cause failure analysis of two tempered glass objects, a
basketball backboard and a pickup truck rear window. Includes a discussion of
Polarimeter surface stress measurements using a Strainoptics Grazing angle Surface
Polarimeter, GASP. Included is a detailed glass fracture analysis which includes
determining the failure origin. This failure analysis study demonstrates how to
analyze tempered glass.
