The discussion centers on the derivation and testing of the stress-strain curve, including inquiries about its complexity, the types of tests applied, and the measurement of shear stress and strain. Participants express curiosity about the relationship between nominal stress and shear strain, as well as the challenges in finding relevant resources.
Participants do not appear to reach a consensus, as there are competing views on the inclusion of shear stress in the discussion and differing levels of understanding regarding the stress-strain relationship.
There are limitations in the discussion, including missing assumptions about the definitions of stress and strain, as well as unresolved questions regarding the relationship between nominal stress and shear strain.

I consider that it is so complicated, but I really wonder how a stress strain curve is derived, what kind of tests are applied and how those tests are applied?
ok but what about shear stress??, the link shared is only about nominal stresses. How is shear strain measured??berkeman said:
You didn't ask about shear stress in your opening post. Sigh. How about you do a quick Google search to see if you can answer your question easily...mertcan said:ok but what about shear stress??, the link shared is only about nominal stresses. How is shear strain measured??
Actually, I would like to ask how can we find the relation between nominal stress and shear strain? I am aware that in some situations nominal stress along x-axis may change nominal strain along x axis, also nominal strain y axis, also shear strain on xy plane for instance. How can we obtain nominal stress along x and shear strain curve? There are not enough sources on internet by the way...berkeman said:You didn't ask about shear stress in your opening post. Sigh.
