摘要: Abstract A large amplitude flexural vibration of a hybrid laminated beam resting on an elastic foundation in thermal environments is investigated. The consists fiber reinforced composite (FRC) layers and piezoelectric (PFRC) actuators. reinforcements are assumed to be distributed either uniformly (UD) or functionally graded (FG) piece-wise type along the thickness beam. motion equations based higher order shear deformation theory von Karman strain displacement relationships. beam-foundation interaction thermo-piezoelectric effects also included. material properties both FRCs PFRCs estimated through micromechanical model temperature dependent. two-step perturbation approach employed determine nonlinear linear frequency ratios beams. Detailed parametric studies carried out investigate property gradient, variation, applied voltage, stacking sequence as well stiffness characteristics
