摘要: Abstract Perforation failure of fibre metal laminate (FML) panels subjected to the localized high intensity blast loading is studied. The FMLs are based on various stacking configurations aluminium alloy sheets and layers woven glass in a polypropylene matrix (GFPP) composite. Finite element models were created using commercial software package Abaqus/Explicit, where constitutive relationships damage composite material described through user-defined subroutine. was modelled as an orthotropically elastic prior initiation growth subsequent instant rate-dependent model. simulated deformation modes found be good agreement with published experimental data. For thin GFPP layers, number dynamic scenarios captured, such petalling, large tensile tearing multiple debonding between layers. A degree correlation back face underlying revealed. Finally, transient behaviour FML during studied discussed.
