Dynamics characteristics and energy absorption of fibre-metal-laminate (FML) thin-walled tubes

Fibre-metal-laminate (FML) hybrid material has an enormous potential to replace metallic materials in vehicle structural applications. In this study the dynamic response and energy absorption capability of FML thin-walled tube were investigated via parametric study using finite element models. The m...
