Abstract Delamination is considered as one of the most critical failure modes which occurs near free edges in laminated composites due to high interlaminar stress. When classical plate theory used determine plane stress, stresses cannot be assessed by this theory, it adopts stress assumption. For that, a three-dimensional finite element analysis adopted calculate in-plane well out-of-plane unde...

The failure mechanism of corrugated sandwich panels under three-point bending is investigated experimentally and numerically using ABAQUS/Standard. Three dominant modes failure, viz. face buckling, yielding core previously reported by others, were also identified here they found to be affected the face-sheet thickness, height corrugation angle panel. It will shown that deformation map, regime b...
