Default Stress-Strain curve for linear elastic material.

Hello everyone,

In my OpenFOAM case, I am doing compression test on a cube geometry and I need to get stress-strain curve. I am assuming linear elastic isotropic material. Stress-strain curve for linear elastic material should show linear behaviour of material (according to the Hook's law). After running simulations I got following values:

sigmaxx, sigmayy, sigmazz, sigmaxy, sigmaxz, sigmayz, and sigmaMagnitude
epsilonxx, epsilonyy, epsilonzz, epsilonxy, epsilonxz, epsilonyz, and epsilonMagnitude

Which value I can use for making stress-strain curve (e.g. sigmaxy-epsilonxy, or sigmaMagnitude-epsilonMagnitude ......etc).

Where (e.g. at the middle of the cube geometry or at the sides of cube geometry etc.) I can plot a line for getting stresses and strains values for plotting stress-strain curve in compression test?

Does anyone have any idea?

Thanks in advance.

Best regards,
