Abstract
<jats:p>Damage behavior of foam core sandwich composites subjected to quasi-static indentation testing was investigated detailedly. Force-displacement curves and the cross-sections of damaged sandwich panels were analyzed. Effects of core thickness, face-sheet thickness and toughness of face-sheet materials were discussed by comparison with different specimens subjected to quasi-static indentation testing. Results showed that damage behavior of sandwich composites had identical feature. Collapse of foam core initially appeared, and then foam core generated crack. Delamination and fiber breakage of upper face-sheet occurred. Finally, the foam core and the face-sh...
