After you have become familiar with a few stress analysis and FEA guidelines made available before attorneys constrained guidelines for engineers, there are a few other things to consider.
• Why has the "need" for FEA engineers been so ... "severe,"
since the 1980s, and before -- just as "crucial" as today in 2025?
• Why have software "improvements" not solved these problems?
• These "chapters" appear in sequence below, until enough are finished to re-org the page.
• Even in a partially free market, how can a shortage exist? That makes the issue moot.
Why work so hard to pretend a non-shortage is a "competency deficiency?"
There will be about a dozen concepts to detail, but time constraints for more important non-FEA research tend to delay putting them into this web site. Patience please. The "problem" is not going to be solved for another 40 years either.
Re-Entrant Corners
The focus on drawings can lead to rushing the drawings where the fillets are not drawn for every re-entrant corner. St. Venant's theorem indicates that these errors can be small if ther are no major load paths through that area. If the mesh is held at the drawing level, this can be a decision made for future designs where this assumption may not apply.
Yet re-entrant corners are still found in major magazines as a showcase for a "good" FE model. And the error can be infinite for even a modest re-entrant corner:
Like in this collage of the following paper's results.
Facets, facets, everywhere
Coming to you soon, how h-level (element segmentation) can introduce an effect similar to the above stress concentrations -- and they are still concentrations until the angle is 180 degrees. Facets are faces that surround pipe interiors and exteriors. Facets are on the edge of a hole in a plate. Facets are everywhere.
