The DME Model (Dynamics of Elastic Membranes) is presented as an effective framework to explore whether part of the gravitational phenomenology observed at galactic and cosmological scales can be interpreted as a structural response of the physical medium rather than as the effect of an additional non-baryonic matter component. The model introduces a scalar parameter κ(x), interpreted as an effective structural rigidity of the medium, which modifies the relation between baryonic density and gravitational potential through a generalized Poisson equation. The formulation preserves the standard Newtonian and relativistic limits in regimes where κ → 0. Qualitative implications for galactic rotation curves, weak gravitational lensing, and large-scale structure are explored. Explicit criteria of falsifiability are formulated, together with a computational protocol for observational testing using publicly available astrophysical data. The model is presented as an effective and testable framework rather than a complete fundamental theory. Its scientific viability depends on its ability to reproduce observational data with parametric economy and internal consistency.
