The dynamic analysis of a functionally gradient material (FGM) beam undergoing large overall motion based on meshless methods is studied in the variable temperature field environment. Considering high-order terms nonlinear coupling deformation which were often ignored previous studies, rigid–flexible coupled (HOC) model rotating FGM with lumped mass established by employing Lagrange’s equations second kind. Compared first-order approximate (FOAC) model, HOC more accurate and has wider scope application. validity point interpolation (PIM) method radial (RPIM) this paper verified comparison simulation results assumed mode (AMM) finite element (FEM). On basis, factors affecting characteristics such as form field, index, location added are discussed. In paper, higher computational efficiency adopted. This study will provide guidance reference for dealing problems engineering, machinery, aerospace, other fields complex
