An experimental and numerical investigation of core damage size in honeycomb sandwich panels subject to low-velocity impact
Composite Structures(2020)
Abstract
•Core damage depth is dependent on the height of the adhesive fillet.•Core damage depth is independent of the dent depth, impact velocity, impactor size and mass.•Core damage depth is independent of the density and configuration of the honeycomb core.•The width of the core damage is the same as the width of the facesheet dent.
