Stress, Failure, and Fatigue Analysis
When failures occur Aiken
engineers determine root cause(s) and propose
solutions to help clients get back up and running.
Furthermore, Aiken advises clients on how to avoid
similar problems in the future.
The following case illustrates
Aiken’s dedication to providing a client
with a complete solution when critical applications
are at stake.
Case:
Fatigue cracks were discovered in a 29,000-ton
press used to manufacture critical components
for jet engines. Aiken was contracted to determine
the cause of the fatigue cracks and predict the
residual functionality of the damaged components.
The malfunction was created through overloading
and general misuse of the equipment. Aiken compiled
and considered Finite Element and Fatigue Analysis
data, which revealed the remaining life of the
cracked components to be less than 5 years. A
senior engineer at Aiken Engineering predicted
that fatigue cracks probably existed in other
critical components as well. This judgment proved
correct, subsequent inspections revealed more
comprehensive damage. Aiken engineers worked with
the client to solve this huge problem. They redesigned
the critical components, assisted in the manufacturing
and QA/QC for the new components, and implemented
an ongoing inspection program to monitor crack
growth until the new components could be installed.
