Energy absorption capability of an aluminum/GFRP hybrid square tube under axial crush and bending collapse

摘要

Energy absorption capability of axial crush and bending collapse of aluminum/GFRP hybrid tubes were investigated. Failure mechanisms of the hybrid tube under the axial compressive load and the bending load were experimentally investigated. For calculating energy absorption capability of axial crush and bending collapse behaviors of the hybrid tube, the modified plastic hinge collapse model and the modified Kecman's model for hybrid tube were suggested, respectively. Two suggested models for the hybrid tube showed a good agreement with the experimental results.
