Behaviour of fibre metal laminates subjected to localised blast loading—Part II: Quantitative analysis

This two part paper examines the behaviour of fibre-metal laminates (FMLs) subjected to localised explosive blast loading. Part I presents the experimental observations of diamond and cross-shaped back face deformation, as well as pitting, global displacement and ring-buckling of the front face are...

Zusammenfassung:This two part paper examines the behaviour of fibre-metal laminates (FMLs) subjected to localised explosive blast loading. Part I presents the experimental observations of diamond and cross-shaped back face deformation, as well as pitting, global displacement and ring-buckling of the front face are also discerned. Part II presents quantitative analysis of the experimental data. When expressed in terms of non-dimensional parameters front and back face displacements fall within one plate thickness of a linear trend line. The threshold impulse for the onset of tearing is found to increase linearly with panel thickness.
