STRESS ANALYSES-FEA

It is often difficult to perform stress or strain analysis of defects with complex characteristics, in complicated structures, or complex material properties, or flaws in pipelines subject to complex loadings. In other cases, results from analysis using mathematical formulations may be overly conservative. Finite element analysis (FEA) can be used to model a variety of different geometries, and complex or multiple load scenarios effectively.

Strain and stress conditions from FEA can be assessed against code limits to determine acceptability. Stress or strain distributions from FEA can be used to determine high loading locations which in turn can be used to design effective repair methods.
