Modelling the Behaviour of Fibre-Metal Laminates subjected to Localised Blast Loading
The modelling particulars of the response of Fibre-Metal Laminates (FML) to localised blast loading are discussed, particularly considering the debonding failure at the composite-metal interface. Attention is paid to the though-thickness transient deformation process in order to interpret the deformation mechanism due to highly localised pressure pulses. The study is based on previously reported experimental results on FML panels comprising different numbers of aluminium alloy layers and different thickness blocks of GFPP material. Good agreement between the experimental results and numerical predictions is demonstrated. A brief comparison between the response of a relatively thin FML panel and a monolithic aluminium alloy plate is presented.
