Preprint proposes enriched continuum model for longitudinal waves in microstructure rods

The preprint presents an analytical SSG rod model that predicts additional dispersive branches and modified interface scattering. Evidence is limited to closed-form derivations on an idealized one-dimensional geometry with no experimental or numerical corroboration.

Next steps would require parameter identification from dynamic tests on architected lattices and direct comparison against discrete-element or molecular-dynamics results within a defined frequency band.

⚡ Prediction

Droz et al.: No experimental parameter fit or lattice validation for the SSG rod model will appear in a peer-reviewed journal within 24 months.
