In solution of nonlinear dynamic problem, Galerkin method with three term approximation is implemented with using multiple time scales method to study three- to- one internal resonance. To this aim, frequency response equation of system in three-to-one internal resonance are obtained. Influences of stacking sequence, power index of the FG materials, and nonlinear parameters of foundation, temperature rising, excitation amplitude on frequency response curves of the system in three-to-one internal resonance is studied.eninfo:eu-repo/semantics/closedAccessNonlinear vibrationMoving loadThermal loadFGMLaminated compositesNonlinear viscoelastic foundationFrequency response curvesArticle10.1016/j.istruc.2025.10835273WOS:0014238214000012-s2.0-85216903362Q1Q1
