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.

A stress-strain curve is a graphical representation of the relationship between the stress applied to a material and the resulting strain. It shows how a material responds to external forces and helps to determine its mechanical properties.
A stress-strain curve is derived through tensile testing, where a sample of the material is subjected to increasing levels of stress until it reaches failure. During this process, the resulting strain is measured and plotted on a graph, with stress on the y-axis and strain on the x-axis.
A stress-strain curve can provide valuable information about a material's mechanical properties, such as its elastic modulus, yield strength, ultimate tensile strength, and ductility. It can also show how a material behaves under different levels of stress and strain, allowing for the prediction of its performance in different applications.
A stress-strain curve is tested through tensile testing, which involves applying a gradually increasing load to a sample of the material until it reaches failure. The resulting stress and strain values are recorded and used to plot the curve.
The shape of a stress-strain curve can be affected by various factors, including the type of material, its composition and microstructure, the testing conditions (such as temperature and rate of loading), and any pre-treatments or modifications applied to the material.
