Talk given at the 5th Industrial Computed Tomography Conference (ICT2014) in Wels, Austria on the 26th February 2014.
This paper presents the first 3D CT assessment of impact damage in coupon size CARALL fibre metal laminates. CT was applied to provide novel 3D insights as to the impact damage produced in both metal and polymer layers of FML.
For the metal layers, the presence of yielding/cracking can be assessed, visualised and localised in 3D. For the composite layers, the impact damage can be segmented and rendered in 3D, showing the different damage mechanisms involved (cracking and delamination).
The distance transform methodology was employed to obtain through thickness damage profiles. These profiles can be used to automatically separate the segmented impact damage based on damage type.
