OK then. What does FEA in that sentence got to do with anything, anyway? With metals and metallurgy, specifically?The comma separates the FEA statement and the general statement that she knows a lot about metals. Now, if I stated that while she performed a FEA on the part she came across a metallic anomaly then you could ascertain a link. The FEA statement goes along with her comment on the stress concentrations because of the machining process and she has vast knowledge on why parts break from her background.
BTW, it's easy to do FEA these days. Super software. Just plug and chug. Back in the day one needed to know alot of Fortran before you could even try to do FEA.
