The honeycomb structure collapse during energy absorption and deformation is considered as one of the important subjects for researchers. In this paper, a combined analytical, numerical and experimental analysis on the collapse load of hexagonal aluminum honeycombs due to buckling or plastic collapse of the unit cells under flatwise compressive loading is performed. To analyze the collapse load, some...
According to the importance of safety, lightweight energy absorbers such as honeycomb structures have drawn researchers’ attention in recent years. In this research, a graded honeycomb structure is proposed in order to reduce head impact injuries during car accidents. Polypropylene polymer is used for the graded honeycomb structure. The structure was modeled by means of Abaqus software and according...
In this study graded honeycomb structure has been introduced as energy dissipation device. This type of energy absorbers can reduce casualty in case of an accident for moving vehicles. In this study energy absorbers design for elevator cabin is considered. A Numerical investigation conducted and results for total absorbed energy, load and acceleration subject to occupant has been presented. Numerical...
