Abstract:
Dynamic Green's functions for a class of layered distributed parameter systems are derived using a new method. The resulting system Green's function, which is comprised of the elemental Green's function of each of the substructures, defines the dynamics of the fully coupled system. Green's functions for sandwiched beams with both identical and different layer properties are derived. The result, which retains the accuracy of the elemental Green's functions, is exact for systems of Euler-Bernoulli beams. The application of the method to systems of other layered structures is immediate as long as the elemental Green's functions of the substructures are known.
