WebMay 14, 2024 · 4.1.6. Stress-strain relation for isotropic material. For a material whose elastic properties are not a function of direction at all, only two independent elastic material constants are sufficient to describe its behavior completely. This material is called isotropic linear elastic. The stress-strain relationship for this material is written as WebMar 21, 2024 · It can be seen as the material’s ability to resist deformation (rigidity), and from a micro perspective, it is the bond strength between atoms and molecules. Two materials with the same deformation (the same strain value), the material with a higher resistance to deformation (a larger elastic modulus) will bear a larger stress.
