“…The increase at smaller oblique angles is likely due to the increase in contact area and the resulting additional frictional energy dissipation. Ochelski and Gotowicki [21] studied the SEA of carbon and glass/epoxy tubes and cones at various inclination angles and observed a significant SEA reduction with increasing inclination angle ( Figure 5.18). The tests were conducted using quasi-static testing and it has to be expected that, during dynamic testing, structures might fail catastrophically due to an increase in peak load.…”

“…The experimental results showed a dependency of the stability of the crushing response and the specific energy absorption on the loading, the geometry of specimen and the material composition. Ochelski and Gotowicki [45] performed an experimental assessment of energy absorption capability between CFRP and GFRP composites. The crush failure load and first peak load in the composite testing increases remarkably with the increase in the number of layers, content of fibres, composite thickness and bending stiffness.…”

Abstract. Collapsible impact energy absorbers play an important role of protecting automotive components from damage during collision. Collision of the two objects results into the damage to one or both of them. Damage may be in the form of crack, fracture and scratch. Designers must know about how the material and object behave under impact event. Owing to above reasons different types of collapsible impact energy absorbers are developed. In the past different studies were undertaken to improve such collapsible impact energy absorbers .This article highlights such studies on common shapes of collapsible impact energy absorber and their impact behaviour under the axial compression. The literature based on studies and analyses of effects of different geometrical parameters on the crushing behaviour of impact energy absorbers is presented in detail. The energy absorber can be of different shape such as circular tube, square tube, and frustums of cone and pyramids. The crushing behaviour of energy absorbers includes studies on crushing mechanics, modes of deformation, energy absorbing capacity, effect on peak and mean crushing load. In this work efforts are made to cover major outcomes from past studies on such behavioural parameters. Even though the major literature reviewed is related to metallic energy absorbers, emphasis is also laid on covering literature on use of composite tube, fiber metal lamination (FML) member, honeycomb plate and functionally graded thickness (FGT) tube as a collapsible impact energy absorber.

“…The energy absorption capability is strongly dependent on the stacking sequence [1] [11]- [13]. Even when the same stacking sequence is adopted, the energy absorption capability changes depending on the cross-sectional features [1] [14]- [16].…”

Quasi-static and dynamic crush tests of a unidirectional carbon fiber reinforced plastic (CFRP) circular tube were performed, and its energy absorption capability was controlled using a doublesided plug. It was revealed in the quasi-static crush test that its energy absorption capability was controlled significantly from 8 to 178 kJ/kg by changing the curvature of the plug. The range of energy absorption covers almost all types of CFRP tube reported in the literature. A dynamic crush test up to 55 km/h was then performed by drop weight impact tests. The energy absorption capability of the CFRP tube in the dynamic crush test was very similar to that in the quasi-static crush test. A simple design concept of energy absorption for a CFRP tube, using the double-sided plug, was proposed.
