Compressive strength - Wikipedia
When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand, if the material compresses and shortens it is said to be in compression.
On an atomic level, molecules or atoms are forced together when in compression, whereas they are pulled apart when in tension. Since atoms in s…Wikipedia · Text under CC-BY-SA license- bing.com › videosWatch full video
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 …
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 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…
