Dear colleagues,
I have received a report from an analysis supplier in which it is stated that the principal strain limit refered to in item D.2.5 of the ISO 13628-7 (2%) may be compared, when applied to the item a) in D.2.4, to the average of principal strains (I'm talking about FEA results here), taken on a line perpendicular to the surface showing a principal strain above 2%.
This approach is looking like a strain linearization, but I found no directions or rules for it anywhere in the text.
As I understand, the strain limit refered to in D.2.5, being applied to a strain gauge reading in a physical test, would only be applied to the surface value in the similar FEA analysis, because the strain gauge only reads a surface value.Is this correct?
Any comments are welcome.
I thank you all for your attention.
Best regards.
