Fiber–Metal Laminate Panels Subjected to Blast Loading

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

“…The observed decrease for the A2T18 panels is due to the sharp decrease in front face debonding with increasing impulse observed in Ref. [26]. The magnitudes of debonding are low, typically below 20% of plate width up to an impulse of 10 Ns.…”

“…6 and also in Ref. [26]. Debonding of the back face is observed, but the inner layers stay together (reducing the average debonding length).…”

“…Langdon et al [26] report the results of analysing the cross-sections of the FML panels. All of the panels are sectioned, photographed and the images are digitised.…”

“…There is evidence of trends for debonding of the back and front faces, but not for debonding of the composite from the internal aluminium layers. In an attempt to quantify the debonding behaviour of the panel, the data from [26] will be examined to two ways:…”

“…The debonded length is defined in Ref. [26] as the difference between the x-coordinates of the points at the tips of the debonded regions (this can also be thought of as the horizontal distance between the two points). It is observed that debonding occurs at every aluminium-GFPP interface.…”
