On axial crushing behavior of double hat-shaped CFRP and GFRP structures

•Axial crushing response of CFRP and GFRP tubes were investigated experimentally and numerically.•Dynamic tensile properties of CFRP and GFRP materials were tested at strain rates ranging from 0.00022 to 800 s−1.•A stacked-shell finite element model, which considered the strain rate dependence of intra-layer properties, was developed.•Complex failure mechanisms of CFRP and GFRP tubes were revealed.
