May 01, 2016· In this study, the numerical model is developed with explicit non-linear finite element code LS-DYNA. Fig. 3 shows the thin-walled beam subjected to lateral impact. The thin-walled beam lays on two cylindrical supports and the diameters and span are R2 and S, respectively.A cylindrical punch with a diameter of R1 and a mass of m impacts onto the beam with an initial velocity of v in the mid-span.

The use of imperfections sets the mode and initiation of collapse of a tube at a specific location and reduces the maximum crush force, hence improving the energy-absorbing characteristics of tubular structures. The types of imperfections discussed include prebuckle, parallel and dished indentations, cutouts, stiffeners, fillers, and wrapping.

It is recommended that consideration be given to including structural collapse into fracture assessment procedures carried out using R6 revision 3 or PD 6493:1991 procedures in order to determine the conditions when enhanced toughness no longer influences structural performance (i.e. when effective "upper shelf" conditions are attained).
