Abstract
Abstract The nonlinear dynamic responses of the fiber-metal laminated beam resting on a tensionless elastic foundation and subjected to a moving harmonic load and thermal load are investigated in the paper. The beam-foundation interaction force that only reacts in compression is established by introducing the hyperbolic tangent function, and the steady temperature field is deduced by solving the one-dimensional steady-state heat transfer equation. The nonlinear governing equations are derived by application of Hamilton principle and solved by finite difference method, Newmark method and Newton-Raphson method. In numerical results, FML beams constrained by different boundary conditions are selected to reveal the dynamic properties of FML beams. The effects of some parameters are discussed in detail, and some meaningful conclusions are concluded.
