Criteria for skin rupture and core shear cracking during impact on sandwich panels
University of Bremen, Germany.

Abstract [en]

Core shear cracking induced by impact on sandwich panels is a detrimental failure mode causing severe loss of structural performance. This paper derives analytical expressions for initiation of skin rupture and core shear cracking during impact on sandwich panels with foam cores. The criteria are successfully validated by comparison with experimental results for a range of thicknesses of skins and cores in panels with carbon/epoxy NCF skins and a Rohacell foam core.
