· The axial crushing of multiwalled (spiral) tubes fabried by roll bending 6060–T5 aluminium alloy sheets was investigated both experimentally and numerically by employing the explicit nonlinear finite element code LS─DYNA. The specimens were divided into two groups. The varying parameter of the first group (specimens 1–5) was the number of spirals
