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...

Abstract This article re-examines the nonlinear vibration and bending responses of porous sandwich cylindrical panels reinforced by graphene platelets resting on elastic foundations in thermal environments. The platelet-reinforced composite (GPLRC) core is assumed to be multilayers, each layer may have different porosity coefficient values achieve a piece-wise functionally graded pattern. By in...

This paper is used the slotting technique to manufacture self-reinforced polypropylene (SRPP) sandwich structure. The crashworthiness characteristics of structures were measured as a function relative density. In this research, particular focus placed on examining energy-absorbing with honeycomb and star cores. It was concluded that SRPP panel core length 60 mm provided best characteristics. Mo...
