摘要：
In order to reveal the mechanical behavior of aluminum foam filled composit material, using the aluminum foam-filled steel/Al clad tube (Al-FFCT) as a research object, we applied Crushable-Foam constitutive model of porous foam material to simulate and analyze the effects of materials and structural parameters, including porosity, radius-thickness ratio, height-diameter ratio, interface bonding state, and layer-thickness ratio of clad tube on the energy absorption capability of the Al-FFCT on ABAQUS platform. Results indicated that the impact bending modes of AI-FFTC are all axial symmetrical deformation and are irrelevant to the structural parameters when the porosity of aluminum foam is less than 90%. Meanwhile, the deformation compatibility and the impact resistance of the composite metals are significantly affected by the layer-thickness ratio and the binder complex form. Hence, flexible customization of energy absorption can be realized by combining the structural parameters. A larger design space is also obtained as compared with the traditional aluminum foam-filled tube. Finally, a new lightweight material is provided for the design of such buffering structures as vehicle bumpers and crash boxes. © 2017, Editorial Department of Journal of HEU. All right reserved.
