Numerical Modelling of Triangular Corrugated-core Sandwich Panel subjected to Impact Loading
In this paper, lightweight aluminium AL2024-O sandwich panels were tested using drop-weight impact tower with lateral impactor to evaluate impact responses and to identify the associated failure mechanisms under various impact loading conditions. The simulations impact responses of triangular corrug...

| Summary: | In this paper, lightweight aluminium AL2024-O sandwich panels were tested using drop-weight impact tower with lateral impactor to evaluate impact responses and to identify the associated failure mechanisms under various impact loading conditions. The simulations impact responses of triangular corrugated-core sandwich panels were presented, which were validated againts the corresponding experimental data. The triangular corrugated-core sandwich panel configurations were studied by using commercial finite element (FE) code,Abagus/Explicit. The FE code is used to develop numerical models by using plasticity with strain hardening and ductile damage criteria, etc., to cover the most representative cases. |
