Overview of Finite Element Analysis (FEA)
Finite Element Analysis (FEA) is a computerized system of theoretical modeling used to predict stress locations and causes of failures in different materials. This method is useful for simulating, modeling, and analyzing problems that could affect complicated systems, such as oil pipelines or oil platforms.
FEA is based on the idea that most engineering problems can be solved more easily by using mesh generation techniques to divide a component into a large number of smaller, finite elements. Each of these finite elements can then be analysed individually. The analysis works by using equations to predict the behavior of each individual object under specific conditions. These individual behaviors are then calculated together to gain an understanding of how the system will behave as a hole under the set conditions.
Some of the things that can be analysed and predicted by FEA include: the effects of stress, damage caused by contact between parts, fatigue and fractures, vibration fatigue, and damage due to fire or heat transfer. The method is particularly useful because it tends to be more accurate than other methods and can examine a complicated system with great precision. Likewise, it can be performed much more quickly than traditional hand calculations.
On the other hand though, use of computerized models has several limitations as well. They are unable to account for things such as: human error in input data, the properties of materials, and geometrical features that could possibly be missed by analysts. Likewise, there is to expected a certain amount of error in every type of numerical analysis, and FEA is no different in this regard. The degree of error in any one analysis is dependant on the type, size, and accuracy of the model used in the analysis.
FEA is covered, along with other fitness-for-service analysis techniques, under API RP 579-1 / ASME FFS-1.

Combining High Resolution In-Line Geometry Tools and Finite Element Analysis to Improve Dent AssessmentsMay/June 2015 Inspectioneering JournalBy Rhett Dotson, P.E. at Stress Engineering Services
Historically, regulations regarding dent severity have been governed by one of two metrics: dent depth or strain. In the case of the former, plain dents with a depth up to 6% of the nominal diameter are permitted in both gas and liquid pipelines. However, many operators typically set stricter limits on dent depth targeting those above a depth of 2% for evaluation.

March/April 2013 Inspectioneering JournalBy Greg Garic at Stress Engineering Services, Inc.
If an operator finds cracking in a furnace waste heat boiler, excessive thinning in an absorption tower, or severe bulging in a converter, FFS assessments—not standard code analyses—are needed to evaluate the unit’s mechanical integrity. FFS assessments, according to the American Petroleum Institute (API), are “quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service component containing a flaw or damage.”
