CORROSION FEATURES Proceeding Of Mechanical Engineering Research Day 2015 (MERD’15).
1. INTRODUCTION
Structures that are deformable such as honeycombs as in Figure 1 are often used as an energy absorber. Honeycomb, in particular, is widely used as it has a relatively strong and stiff properties, as well as its good energy absorption characteristics and cost-effective. Previous researcher has found that the energy absorption of tubular structures can be increased by the addition of filler such as foam and wood [1,2,3,4,5,6]. These findings were found in both axial out-of-plane and lateral in-plane crushing mode. For lateral loading on a single hexagonal ring, it has been found that the collapse load in ring compressed across face is higher than that compressed across corner by a factor of 1.8 [7]. The objective of this paper is to find the energy absorbed by multi-cells honeycomb hexagonal-shaped and compare it with the single hexagonal ring theory. Figure 1 Multi-cell honeycomb2. METHODOLOGY
Results that presented later used aluminum honeycomb 3003-H18 with the data in Table 1. The basic collapse mechanisms of the hexagonal ring were introduced in [7]. As shown in Figure 2, there are two methods to compress the specimen laterally namely corner and face. By assuming the model to be rigid perfectly plastic, some formulas were derived. The formulas derived by considering the mode of deformation stages. During the compression across faces, the first mode of deformation is known as Mode 1 Phase 1 M1P1. In the second phase, there are two modes of deformation, namely Mode 2 Phase 1 M2P1 and Mode 2 Phase 2 M2P2 is observed and formulated. Table 1 Data for aluminium honeycomb 3003-H18 Properties Data Dimensions 100mm x 100mm x 100mm Poisson ratio 0.33 Yield Strength 115.8 MPa Figure 2 Compression method under lateral loading Figure 3 shows the basic collapse mode of honeycomb under lateral loading. During compression, all shows a linear-elastic behaviour at the first regime. It is then followed by the second regime in which a plateau of roughly constant stress is observed. In the final regime, a steeply rising stress is detected [7].Parts
