Abstract

Dynamic axisymmetric buckling of cylindrical shells, loaded dynamically by a Kolsky bar, is studied in order to analyse the influence of stress wave propagation on the initiation of buckling. The considered specimens are made of an aluminium alloy which has linear strain hardening and displays the Bauschinger effect. The acceleration wave speeds are obtained assuming the Tresca yield criterion. The deformation process is analysed by a numerical simulation using a discrete model for the shell and the theoretical predictions are compared with some published experimental data. It is shown that the different modes of f
