The following study addresses the problem of analysing the behaviour of a hybrid composite-metal component, especially in the axial crush absorbing energy field. An aluminium circular tube coupled with Carbon Resin Fibre Plastic (CFRP) lamination was investigated. The study is divided in two, an experimental campaign of different tube configurations using a drop tower testing system and numerical simulations in order to capture and correlate the dynamic of the crushing process. Each configuration has been reproduced and simulated in the finite element code LS-Dyna.
Il seguente lavoro tratta l’analisi del comportamento a crash di tubi ibridi metello-composito, nello specifico il comportamento di assorbimento di energia durante un impatto assiale. È stato ispezionato il comportamento di un tubo in alluminio rinforzato tramite laminazione di pre-impregnati in fibra di carbonio. Lo studio si è diviso in test sperimentali utilizzando il sistema “torre di caduta”, in differenti configurazioni di laminazione, e la correlazione del comportamento tramite simulazioni numeriche. Tutte le configurazioni sono state simulate tramite il codice ad elementi finiti LS-Dyna.

Abstract
The following study addresses the problem of analysing the behaviour of a hybrid composite-metal component, especially in the axial crush absorbing energy field. An aluminium circular tube coupled with Carbon Resin Fibre Plastic (CFRP) lamination was investigated. The study is divided in two, an experimental campaign of different tube configurations using a drop tower testing system and numerical simulations in order to capture and correlate the dynamic of the crushing process. Each configuration has been reproduced and simulated in the finite element code LS-Dyna.File | Dimensione | Formato | |
