Failure of a design can take many forms, including:
- Premature fatigue failure
- Inability to withstand extreme in-service loads
- Unacceptable effects on surroundings (e.g. vibration, noise, leaks)
- Required level of performance is not achieved
Eatec Engineering Analysis provides an efficient approach to the investigation of in-service failure, and the identification of the cause of the problem and the changes required to ensure the design performs satisfactorily.
Depending on the particular problem, failure investigations commonly involve using finite element analysis (FEA) to assess the structure and identify the cause of the failure, or testing, or a combination of FEA and testing.
In some cases, finite element analysis (FEA) is used to identify the cause of the failure or problem, and to determine the design changes required to solve the issue.
In other cases, the cause of the problem can be identified by instrumenting the structure using accelerometers or strain gauges, and taking measurement whilst it is operating. Using finite element analysis (FEA), potential design modifications can then be evaluated to identify the most beneficial changes. Where testing is required, Eatec Engineering Analysis works with long term associates who are highly experienced and knowledgeable.
Examples of failure investigations performed by Eatec Engineering Analysis include:
- Fatigue failure of process equipment
- Failure of ship berthing fenders
- Excessive vibration of process plant
- Leaking of gaskets
- Failure of bearings
Normally once the cause of the failure or problem has been identified, Eatec Engineering Analysis works with the client to identify the most efficient design changes which will resolve the issue. However, in some cases, Eatec Engineering Analysis’s findings are used to support a claim against a supplier or third party.
Eatec Engineering Analysis has undertaken failure investigations for clients in many industries, including:
- Material handling
- Power generation
