  4. Abstract:
  5. The free vibration properties of a sandwich beam with axially graded facings and a magnetorheological fluid core are studied. The facings and core are modeled using the Euler–Bernoulli and Timoshenko beam theories, respectively. The problem is discretized using the Rayleigh–Ritz method. The approached complex eigenmodes method is implemented for solving the resulting nonlinear eigenvalue problem numerically. The effects of multiple parameters, i.e., facings' material distribution, functionally graded material's gradient index, boundary conditions, constraining and core layers’ thickness, and magnetic field effect on the free vibration properties, are thoroughly studied. The obtained results reveal these parameters' significant impact on the frequency and loss factor of the system. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature
