Forced Vibration Behaviour of Elastically Constrained Graphene Origami-Enabled Auxetic Metamaterial Beams

Mathematical and Computational Applications, Journal Year: 2025, Volume and Issue: 30(1), P. 5 - 5

Published: Jan. 7, 2025

This paper explores the vibration behaviour of an elastically constrained graphene origami-enabled auxetic metamaterial beam subject to a harmonic external force. The effective mechanical properties are approximated using micromechanical model trained via genetic algorithm provided in literature. three coupled equations motion solved numerically; set trigonometric functions is used approximate displacement components. accuracy proposed confirmed by comparing it with natural frequencies simplified non-metamaterial structure available Following this validation, investigation extends investigate forced response beam, examining influence origami distribution pattern and content, folding degree, linear shear layer stiffness, geometrical parameters on dynamic structure. results generally highlight considerable effect layer, modelled as Pasternak foundation, beams.
