[Dynamique des poutres sandwich CNTRC inclinées sous une masse en mouvement avec influence de l’agglomération des CNT]
La dynamique des poutres composites inclinées renforcées par des nanotubes de carbone (NTC) sous une masse en mouvement avec l’influence de l’agglomération des NTC est étudiée. Les poutres sont composées d’un noyau homogène et de deux couches composites frontales dont les propriétés effectives sont estimées par l’approche Eshelby–Mori–Tanaka. Une nouvelle formulation par éléments finis est formulée et utilisée pour établir l’équation du mouvement. La réponse dynamique est calculée pour une poutre simplement supportée par la méthode de Newmark. Les résultats révèlent le rôle important de l’agglomération des NTC sur la réponse dynamique. Les effets de la vitesse de la masse, de l’angle d’inclinaison et des paramètres d’agglomération sur le comportement dynamique sont étudiés en détail.
Dynamics of inclined carbon nanotube (CNT) reinforced composite beams under a moving mass with influence of CNT agglomeration is studied. The beams compose of a homogeneous core and two composite face layers with effective properties being estimated by Eshelby–Mori–Tanaka approach. A novel finite element formulation is formulated and used to establish the equation of motion. Dynamic response is computed for a simply supported beam by Newmark method. The result reveals the important role of the CNT agglomeration on the dynamic response. The effects of the mass velocity, inclined angle and agglomeration parameters on the dynamic behavior are investigated in detail.
