Efficacy of invariant surface energy density for multiscale shifting of volume energy density

► Uniaxial test data are approximated as monoscale average material property of the specimen. ► Macroscopic and microscopic material properties are different, but they can be related. ► Surface energy density (SED) establishes scale shifting law to relate macro-micro effects. ► The SI system belongs to the homogeneous case of the scale shifting law. ► Multiscaling is inherent to the sustainability and stability of material microstructure.
