| Abstract | ||
| This research develops a higher-order vibrational model for graphene origami-reinforced composite cylindrical panels operating in thermal environments. The formulation incorporates foldability-dependent constitutive relations through modified micromechanical coefficients that capture temperature-induced property transitions. Foldability concept is used for the graphene origami in which transforms graphene from a 2D material into a reconfigurable 3D platform, merging nanoscale precision with macroscale functionality. The core innovation leverages graphene's geometric reconfiguration capability—transforming 2D sheets into programmable 3D architectures to achieve synergetic nanoscale precision and macrostructure functionality. Kinematic relations in cylindrical coordinates integrate higher-order bending, transverse shear, and thickness stretching functions. Governing equations derive from Hamilton's principle, explicitly incorporating pre—stress from thermoelectro- magnetic loads. Vibration suppression correlates with increased crease density and thermal exposure, while origami concentration enhances damping capacity. A diminish in vibration responses is detected with an increase in foldability parameter and thermal loads. An enhanced output is detected with an increase in the origami content and decrease in the folding parameter. | ||
