Blast response of metal composite laminate fuselage structures using finite element modelling

Low-impulse blast behaviour of fibre-metal laminates

“…To date, there is very limited numerical work published on the blast behaviour of FMLs. Kotzakolios et al [18] investigated the blast response of a typical commercial fuselage for two material configurations, aluminium and GLARE, using LS-DYNA. By using ABAQUS/Explicit, Karagiozova et al [19] investigated the blast resistant capabilities and interpreted the deformation and failure mechanisms of FML panels under highly localised blast loading.…”

Modelling of the low-impulse blast behaviour of fibre–metal laminates based on different aluminium alloys

“…Using the ALE approach, air and the detonation products may be described using an Eulerian formulation in a gaseous domain, while the structural response can be treated in a structural domain. A coupling algorithm for the fluid-structure interaction is then employed to connect the two domains [14,15]. However, this approach requires considerably more computational time, especially for ABAQUS/Explicit.…”

“…This work also included the numerical verification process for 50, 75, 100, 150 gram of explosive, and 3 discusses the corresponding failure modes and strain rates. Later, Kotzakolios et al [14] extended their research to investigate the damage induced in a typical commercial fuselage based on aluminium and GLARE, when subjected to an explosive charge. Simulations were performed for different charge locations in three stages: an initialization phase, a blast phase and a final phase.…”

The blast response of composite and fibre-metal laminate materials used in aerospace applications

“…Various explosion scenarios (including analysis of, for example, different charge locations on board aircraft, and effect of altitude on cabin pressure) should be modelled using hydrodynamic models. Examples of explosion modelling using commercially available codes such as Autodyn and, more recently, LS Dyna, are given in Refs [7] and [8], respectively. The spatial and temporal blast loading characteristics are highly variable-depending upon (among other things) the location of the explosion, the aircraft geometry and the propagation media (for example, was the explosion in free air, in a partially filled luggage container, or perhaps inside a recently filled fuel tank?).…”
