In this study, the transient dynamics of a sandwich plate with post impact zone is examined. The dynamic response of the sandwich plate is simulated by using the finite element code ABAQUS. The damage mechanics approach implemented into ABAQUS via cohesive elements is applied to model the debonding propagation under impulsive loading. To demonstrate the effectiveness of the FE model developed, a foam-cored sandwich plate with an initial penny-shaped impacted region is modelled. The influence of the skin-to-core debond on the global nonlinear dynamics of the sandwich plate is studied in detail.


The main results of this paper have been previously presented by the authors as an oral presentation “Effects of a skin/core debond on the dynamics of impacted sandwich plates” at the 12th Conference on Dynamical Systems - Theory and Applications, DSTA-2013, December 2-5 Lodz, Poland and they contributed as an extended abstract to the conference proceedings. The second author would like to mention that this research was co-financed by Ministry of Science and Higher Education within the statutory research number S/20/2013.
