• Resumen

  • This paper aims to report an enhanced mechanistic analytical model to account for the geometry of a concentric cylinder structure, the effect of an elastic bonding layer, and mechanical boundary conditions on the magnetoelectric response. The elastic properties and the geometry of the bonding layer were added into the magneto-electro-elastic effective media theory by modifying the continuity condition through the introduction of a normalized stiffness parameter. Results from this investigation can be applied to the development of efficient energy harvesters or frequency-consistent magnetic field sensors by manipulating the mechanical and bonding conditions.
