26.2: Stress and Strain in Tension and Compression
Jul 20, 2022 · For compressive strains, if we define \(\delta l=l_{0}-l>0\) then Equation \ref{26.2.3} holds for compressive stresses provided the compressive stress is not too large. For many materials, Young’s Modulus is the same when the material is under tension and compression.

Stress–strain curve - Wikipedia
Generally speaking, curves that represent the relationship between stress and strain in any form of deformation can be regarded as stress–strain curves. The stress and strain can be normal, shear, or a mixture, and can also can be uniaxial, biaxial, or multiaxial, and can even change with time. The form of deformation can be compression, stretching, torsion, rotation, and so on. If not mentioned otherwise, stress–strain curve typically refers to the relationship between axial norm…
