Abstract A combined experimental, analytical and numerical/FEM study on the quasi-static axial crushing of thin-walled aluminum S-rails is presented. Quasi-static test was performed on S-rails with a prescribed cross-head speed 10 mm/sec. Finite element models were developed and found to reproduce the crushing response to a significant degree of accuracy with respect to the onset of collapse, the subsequent localization of plastic deformation and the overall energy absorbing capability. With the failure parameters calibrated from uniaxial tensile tests, FEM simulation can also be used to predict the fracture onset. Based on a simplified model, an analytical solution for the force-deflection response was developed, which can be applied to an early design stage of the “S” frame. Finally, the same problem was solved by means of CrashStudio and comparisons were made with some known solutions.
